1235 Jefferson Davis Highway
Arlington, Virginia 22202
Used by Permission
1. Never drop cylinders or permit them to strike each other violently.
2. Cylinders may be stored in the open, but in such cases, should be protected against extremes of weather
and, to prevent rusting, from the dampness of the ground. Cylinders should be stored in the shade when
located in areas where extreme temperatures are prevalent.
3. The valve protection cap should be left on each cylinder until it has been secured against a wall or bench, or
placed in a cylinder stand, and is ready to be used.
4. Avoid dragging, rolling, or sliding cylinders, even for a short distance; they should be moved by using a
suitable hand-truck.
5. Never tamper with safety devices in valves or cylinders.
6. Do not store full and empty cylinders together. Serious suckback can occur when an empty cylinder is
attached to a pressurized system.
7. No part of cylinder should be subjected to a temperature higher than 125°F (52°C). A flame should never be
permitted to come in contact with any part of a compressed gas cylinder.
8. Do not place cylinders where they may become part of an electric circuit. When electric arc welding,
precautions must be taken to prevent striking an arc against the cylinder.

SECTION 1
DESCRIPTION AND SPECIFICATIONS
1-1 GENERAL DESCRIPTION
The Model 890 Ultraviolet Analyzer is
designed to determine continuously the
concentration of the component of interest in
a flowing gaseous mixture. The analyzer is
capable of measurement in the 50 to 5,000
ppm range for SO2 and 100 to 5,000 ppm for
Cl2.
Optical Bench
The ultraviolet source emits a pulsed (30 Hz)
beam of energy. This energy is split by a
beam splitter, each beam being directed to
pairs of detectors before and after the sample
cell.
One of the unique features of the Model 890
is the use of spectrally selective,
“Transflectance”© mirrors. These mirrors
isolate the sample and reference spectral
passbands for the detectors. They reflect
energy below a wavelength region and
transmit the remaining, higher wavelengths,
all with much lower energy loss than the more
commonly used bandpass interference filters.
Four detectors are used in this system, two
before the sample cell (sample before [Sb]
and reference before [Rb]) and two after
(sample after [Sa] and reference after [Ra]).
Sb and Sa receive energy in the specific
wavelength regions depending on the
application (265 to 310 nm for SO2, 310 to
355 nm for Cl2), Rb and Ra in the 310 to 355
nm region for SO2 and 355 to 400 nm for Cl2.
These four detectors measure the component
of interest (COI) concentration and correct for
NO2 interference and UV lamp fluctuations.
The difference between detector
determinations is the COI concentration,
following this formula:
Rosemount Analytical Inc.
A Division of Emerson Process Management
COI = [f(Rb)-Sb]-[f(Ra)-Sa]
where:
Ra, Rb, Sa, Sb = signals from those
detectors so identified
f = attenuation factor for the reference
signal, adjusted to compensate for NO2
interference.
The sample gas is introduced to the sample
cell, and the COI absorbs ultraviolet energy in
proportion to the concentration in the gas. The
difference between the signals of the
detectors located at both ends of the sample
cell determines the concentration of COI in
the sample.
Additionally, the adjacent (non-COIabsorbing) reference wavelengths are used
as a baseline for measurement and correction
of sample interferent components, particularly
NO2.
Readout is on a 16-character,
LED-backlighted liquid crystal display. COI
concentration data is presented in parts per
million, percent of composition, or percent of
fullscale. Additionally, 0 to +5 VDC output for
a potentiometric (voltage) recorder and 0 to
20 mA or 4 to 20 mA isolated current output
(maximum load 700 ohms) are provided as
standard.
A case heater with fan assembly maintains
proper operating temperature.
Linearization
A linearizer, based on a fourth-order
polynomial, is incorporated in the electronic
circuitry. By turning the linearizer ON and
entering the correct coefficients, an output
linear with concentration is obtained.

WARNING
POSSIBLE EXPLOSION HAZARD
This analyzer is of a type capable of analysis of sample gases which may be flammable. If used for analysis of such gases,
the instrument must be protected by a
continuous dilution purge system in accordance with Standard ANSI/NFPA 4961989, Chapter 8.
WARNING
TOXIC GAS HAZARD
This instrument measures toxic gases.
Ensure gas lines are leak-free and properly
vented. Inhalation of toxic gases is highly
dangerous and could result in death.
Also, exhaust gas from this instrument is
toxic and equally dangerous. Exhaust
must be connected either to its original
source or an appropriate outside vent using ¼-inch (6mm) tubing minimum.
Rosemount Analytical Inc.

If explosive gases are introduced into this
analyzer, the sample containment system
must be carefully leak-checked upon installation and before initial startup, during
routine maintenance and any time the integrity of the sample containment system
is broken, to ensure the system is in leakproof condition. Leak-check instructions
are provided in Section 2-8 on page 2-5.
Internal leaks resulting from failure to observe these precautions could result in an
explosion causing death, personal injury
or property damage.

2-6 CALIBRATION GAS REQUIREMENTS
Analyzer calibration consists of setting a zero
point and one or more upscale points.
All applications require a zero standard gas to
set the zero point on the display or recorder
chart. If the factory Calibration and Data
Sheet (included with the drawings at the end
of the manual) specifies a background gas,
use this as the zero gas. If a background gas
is not specified, use dry nitrogen for the zero
gas. Ideally, span gas should be between
75 % and 100 % of the fullscale span.

2-7 SAMPLE HANDLING SYSTEM
Many different sample handling systems are
available, either assembled completely or as
loose components. The type used depends
on the requirements of the particular
application and the preferences of the
individual user. Typically, the sample
handling system incorporates such
components as pumps and valves to permit
selection of sample, zero standard and
upscale standard gas; needle valve in
sample-inlet line for flow adjustment;
flowmeter for flow measurement and/or
indication of flow stoppage; and filter(s) to
remove particulate matter.

2-8 LEAK TEST PROCEDURE
WARNING
POSSIBLE EXPLOSION HAZARD
This analyzer is capable of analyzing sample gases which may be flammable. If
used for analysis of such gases the instrument must be protected by a continuous dilution purge system in accordance
with Standard ANSI/NFPA 496-1989 (Chapter 8).
If explosive gases are introduced into the
analyzer, the sample containment system
must be leak checked upon installation
and before initial startup, during routine
maintenance and any time the integrity of
the sample containment system is broken,
to ensure that the system is in leak proof
condition.
Internal leaks resulting from failure to observe these precautions could result in an
explosion causing death, personal injury
or property damage.
The following test is designed for sample
pressure up to 10 psig (69 kPa).
1. Supply air or inert gas such as nitrogen at
10 psig (69 kPa) to analyzer via a flow
indicator with a range of 0 to 250 cc/min
and set flow rate at 125 cc/min to the
sample inlet.
2. Seal off sample outlet with a cap.
3. Use a suitable test liquid such as SNOOP
(PN 837801) to detect leaks. Cover all
fittings, seals or possible leak sources.
4. Check for bubbling or foaming which
indicates leakage and repair as required.
Any leakage must be corrected before
introduction of sample and/or application
of electrical power.
Rosemount Analytical Inc.
A Division of Emerson Process Management
NOTE
Do not allow test liquid to contaminate cell
or detectors and UV source windows.
Should this occur, follow instructions in
Section 6-1 on page 6-1 to clean the cell.
2-9 SAMPLE FLOW RATE
Recommended sample flow rate is 1 to 2
SCFH (500 to 1000 cc/min). A subnormal
flow rate will not affect readings but may result
in an undesirable time lag. However, an
excessive flow rate can result in cell
pressurization.
Assume that two cell volumes are required to
flush any cell. Approximate flushing time for
the Model 890's 12-inch cell at atmospheric
sampling pressure (i.e., the outlet of the cell
venting to atmosphere) is approximately 12
seconds.
Flushing time is inversely proportional to flow
rate.
The primary effect of flow rate, other than
flushing time, is cell pressure. Due to
restrictions in exit flow configuration, an
increasing flow rate increases sample
pressure in the cell.
In all cases, the effect of pressure on readout
is eliminated if the same flow rate is used for
the measured sample as well as for the zero
gas and span gas.
Note that at higher flow rates the nonlinearity
of the calibration curve increases, because of
increase in sample cell pressure. Therefore, if
higher flow rates are required, the calibration
curve should be redrawn at the higher rate.
At flows up to 2 CFH (1 L/min), gaseous
sample temperatures are equilibrated to
instrument temperature regardless of stream
temperature. At extremely high flow rates,
this may not be true, but no such effect has
been noted up to 18 CFH (9 L/min).

3-6 RANGE PARAMETERS
a.
d.
In the [GAIN=X] display, an amplifier gain
of 1, 2, 4, 8 or 16 can be selected for
each range with the ↑ or ↓ key
depending on the sensitivity desired.
Range 3 is normally the least sensitive
range.
Range Selection
See Figure 3-6 on page 3-11. There are
several range parameters that may be
changed. The first display [RANGE: #
CMP NNN →] allows RANGE 1, RANGE
2 or RANGE 3 to be selected with the ↑ or
↓: key. Of these three independent
ranges, RANGE 3 should always be the
least sensitive range (highest fullscale
range).
b.
c.
Other ranges are generally set with gains
that are proportional to their relative
fullscale spans. Thus, if range 1 is 0 to
50 ppm and range 3 is 0 to 500 ppm, then
the respective gains will usually be 8 and
1. If 5000 ppm is being measured, gain is
x1 and the instrument is set for Low.
Linearization
The Model 890 permits entry of different
sets of linearizing coefficients (Section 312 on page 3-15) for each range. Or, if
desired, one set of linearizing coefficients
may be used for all three ranges when the
dynamic range ratio is 3:1 or less. If only
one set of coefficients is used, this set
should always be entered in Range 3.
Coefficients placed in Range 3 will
automatically be used for Range A (All).
e.
NOTE
Any designation other than the component of interest that was configured
to measure will have no effect on the
analyzer's performance. It continues
to measure the configured COI.

Range, Fullscale
In the [FS=XXXX ppm *] or [FS=XX.X %
*] display, up to a four digit fullscale value
is entered in ppm (parts per million).
Note: The instrument will not allow the
user to enter a fullscale value in the
RANGE, FS screen [FS = XXXX ppm]
that is less than the CAL GAS value
entered in the [CAL GAS = XXXX] screen.
Conversely, the user cannot enter a value
in the [CAL GAS = XXXX] screen that is
larger than the fullscale value entered in
the [FS = XXXX ppm) screen.
Component of Interest
UV methodology may be used for
measuring a variety of components.
Therefore, the software allows the user to
configure the display to reflect whatever
component is being measured. This
component of interest is designated by a
3-digit group of letters or numbers. This
gas name or designation may be selected
for each range by placing the cursor
under the desired digit [NNN] and
selecting a letter or number with ↑ or ↓
key. This name will appear on the display
when the analyzer is in the RUN mode.

3-12 LINEARIZATION
SO2 ranges from 0 to 50 ppm through 0 to
200 ppm and Cl2 ranges from 0 to 1000
ppm through 0 to 200 ppm are linear within
±1% accuracy, and do not require correction (although their linearities are improved with the fourth order polynomial
corrections). The uncorrected 0 to 5000
ppm range is very non-linear, but is corrected to better than ±1% of fullscale with
a fourth order polynomial.
The Model 890 Analyzer can be operated in
linear and non-linear mode. Linearization can
be toggled ON/OFF with the ↑ or ↓ key in
the Linearization Mode Screen (see Figure
3-8 below and Table 3-1 on page 3-16). In
the OFF position, linearization is disabled for
all ranges. In the linear mode, the component
of interest is measured in engineering units,
either ppm (parts per million) or % (percent of
composition). In the non-linear mode, the
component of interest is measured is in %FS
(percent of fullscale).
The analyzer is linearized with the following
fourth-order polynomial:

All Range
The “All” range is a special feature that
allows the user to use Range 3
coefficients for all three ranges. It should
only be used over dynamic ranges of 3:1
or less. If Range A is selected in the
Linearization Mode, the microprocessor
will use the coefficients in Range 3. Also,
if the linearizer is ON and in Range A, the
microprocessor will use the GAIN and
TIME CONSTANT from Range 3,
regardless of the GAIN and TIME
CONSTANT selected for Ranges 1 and 2.
b.
Non-Standard Ranges and Coefficients
When ordered, special linearization
coefficients for non-standard fullscale
ranges are entered in the appropriate
range(s) at the factory. If one set of
linearization coefficients has been
ordered and a range has not been
specified, these coefficients will be for
Range 3.
The user may want the display to read in
engineering units (ppm). This response is
linear over the operating range.
The following coefficients will make no
correction to the straight line response,
but will cause the analyzer to display
engineering units:
A0 = 0.00000
A1 = 1.00000
A2 = 0.00000
A3 = 0.00000
A4 = 0.00000
To calculate linearization coefficients
other than those installed at the factory,
either 11 or 21 data points should be
taken. (If urgent, a curve can be created
with as few as 4 points. This should be
considered temporary and a more
accurate curve made with more points
should be created as soon as possible.)
Rosemount Analytical Inc.
A Division of Emerson Process Management
These data points can be obtained with
an accurate gas divider or other flow
mixing device. Before calculating
coefficients, the data must be normalized
to ranges of 0 to 1 units for both % and
concentration readings. Then the axis
must be reversed as illustrated in Figure
3-10 on page 3-18 and Figure 3-11 on
page 3-18. A multiple linear regression is
then used to calculate coefficients. (For
example: If the range is 0 to 5000 ppm
and readings are 0 to 100%, then divide
all of the concentrations by 5000 and the
readings by 100. Put the normalized
concentrations on the Y-axis and the
normalized readings on the X-axis.
These data points can be entered into any
program capable of computing a fourth
order polynomial curve. This curve will be
the mirror image of the curve on the
application sheet at the back of the
manual, however the linearization
coefficients will be different. Use the
coefficients calculated with the curve for
linearization coefficients. Use these
coefficients to solve the following
equation:

After taking the data points, the user may
determine coefficients for user-specific
gas by either using any program capable
of calculating a fourth order curve fit or
calling the factory to have the specific
coefficients calculated.
When entering user-determined
coefficients, note that the microprocessor
only recognizes five significant figures to
the right of the decimal point (i.e.,
0.12345). Also, the user should ignore the
three non-significant digits as they may
change value while the significant digits
are being changed. The values of the
non-significant digits do not affect the
instrument's linearity.

3-13 ALARM
The Alarm consists of two single point,
field-programmable high or low outputs with a
deadband of up to 20% of fullscale. The two
alarm setpoints are programmable for one
range selected, and are dimensionless. The
alarms can be set with one alarm HIGH and
one alarm LOW, both alarms HIGH or both
alarms LOW. This option is completely user
configurable (See Figure 3-12 on page 3-20).
The Status Display will reflect an alarm
condition should one occur. When the
instrument is in alarm condition (exceeding
the alarm setpoint), the latch associated with
the alarm is set. When the alarm condition
clears, (run mode value is less than the alarm
setpoint plus the deadband) the latch is reset.
The high alarm is determined when RUN
mode value exceeds the alarm setpoint. The
alarm is cleared when run mode value is less
than alarm setpoint minus the deadband.
Rosemount Analytical Inc.
A Division of Emerson Process Management
The low alarm is determined when the run
mode value is less than the alarm setpoint.
This alarm is cleared when the run mode
value is greater than the alarm setpoint plus
the deadband.
ALARM 1 and ALARM 2 can be toggled with
the up and down arrows to either AT
(automatic) or MAN (manual). In the AUTO
(automatic) setting, an alarm relay will be
activated should an alarm condition occur.
Alarms are calculated in the AUTO mode on
the basis of parameter settings. The MANUAL
mode is the test mode and alarms are not
scanned by the CPU. In the MANUAL (test)
mode, the ALARM ON/OFF can be toggled
with the up and down arrows to set and reset
the alarm latch.
The Fail-Safe not only sets the alarm when an
alarm condition is present, but also in the
event of a power outage.

3-15 AUTO ZERO/SPAN
Refer to Figure 3-15 on page 3-25. The Auto
Zero/Span allows automatic, unattended
calibration at set intervals. The option has six
contact closures, four of which are field
programmable for frequency and duration of
the calibration cycle (span 1, span 2, span 3
and zero). Meanwhile, the other two contact
closures indicate insufficient zero and span
adjustments and also drift limits for zero and
span, if activated.
The auto zero/span [AUTO-CAL: ON] display
allows the user to select ON or OFF to turn
the Auto Zero/Span “on” or “off”. Toggling
from OFF to ON resets the timers for the Auto
Zero/Span. To reset the timers when the Auto
Zero/Span is “on”, toggle from ON to OFF to
ON.
The sample and hold [SH: YES] display
allows the user to select YES or NO to turn
the automatic sample and hold “on” or “off”.
When the sample and hold feature is “on”, the
recorder and Current Output do not get
updated until the calibration sequence is
completed.
The range selection [RANGE: 1Y 2Y 3Y]
display allows the user to select the ranges
which will be automatically calibrated with
span gas by using the → arrow to move the
cursor to the desired range and using the ↑ or
↓ key to select Y (yes) or N (no) for each
range. The zero for all three ranges will be
calibrated at each interval regardless of
range(s) selected.
The initial delay [DELAY nnn HR] display
allows the user to select the amount of time
until the first automatic calibration occurs. This
is the initial delay until the automatic cycle
starts. At this time a zero and span calibration
is made regardless of selection. If a zero
delay is selected there will be an automatic
two minute delay.

before the calibration starts for zero and span
or the amount of time for sample gas to flow
through the analyzer before run mode values
are recorded when the sample and hold
feature is selected. The analyzer is calibrated
during the final minute of purge time. During
the remaining purge time the signal is
modified according to previous calibration
data.
The repeat zero [RPT ZERO nnn HR] display
allows the user to select the amount of time
between zero calibrations. This is the amount
of time after the initial calibration before the
zero calibration is repeated without repeating
the span calibration.
NOTE
Each time an auto span calibration is
made, a zero calibration is also made regardless of selection.
During the auto zero/span sequence, the
time constant is set to one second. Upon
completion of the calibration sequence,
the time constant is reset to the value chosen in Range Parameters. The keyboard is
disabled during the auto zero/span sequence.
In order to engage the Auto-Cal function
with the Remote Range I/O, the Auto-Cal
function must be disabled by toggling
AUTO-CAL to OFF in the [AUTO-CAL:OFF]
display.
The repeat span [RPT SPAN nnn HR] display
allows the user to select the amount of time
between span calibrations. This is the amount
of time after the initial span calibration before
this calibration is repeated.
The [DRIFT LIMIT: ON] display allows the
user to determine the maximum amount of
span and zero drift allowable. The [ZR-DFT: ±
XX%] or [SP-DFT ± XX%] display allows the
user to select the percentage of fullscale by
which the analyzer is allowed to drift from the
reference span or zero calibration values. The
maximum zero drift limit is 10% fullscale and
the maximum span drift is 15% fullscale.

3-17 INTERFERENCE BALANCE
a.
SO2 Measurement
The Model 890 analyzer may be
calibrated for a dynamic interferent gas
rejection ratio of up to 1000:1 for samples
containing single, binary or multiple
interferents. This calibration is initially
done at the factory, and generally is a
one-time adjustment.
Re-adjustment in the field should be done
only if: (1) The optical filters are replaced
or (2) the sample stream composition has
changed drastically from the original
composition.
b.
Cl2 Measurement
Use of the Model 890 for Cl2
measurement require a stable
concentration of interferent gas for the
compensation factor to remain accurate.
Otherwise, displayed readings are not
dependable.
Adjustment is An electronic adjustment,
which can be accessed through the
INTERFERENCE CAL function in the
MODE menu structure (see Figure 3-4 on
page 3-7).
The balance adjustment is an electronic
adjustment. If the interference setting is
changed, the balance potentiometer can
be used to balance the system. This is a
fine adjustment.
If more adjustment than the potentiometer
can provide is necessary, the iris can be
used to balance the system to zero. See
Section 5-2 on page 5-2.

ROUTINE OPERATION AND THEORY
4-1 ROUTINE OPERATION
First set the range for desired operating
range: 1, 2, or 3. Then follow the steps for
zero and span (Sections 3-8 on page 3-13
and 3-10 on page 3-13). Next supply sample
gas through the instrument. The Model 890
will now automatically and continuously
analyze the sample stream.
As a check of instrument performance, it is
recommended that the operator keep a log of
the zero/span status (percentage of
potentiometer value).
4-2 RECOMMENDED CALIBRATION
FREQUENCY
Maximum permissible interval between
calibrations depends on the analytical
accuracy required and cannot, therefore, be
specified. It is recommended initially that the
instrument be calibrated once every 24 hours
and that this practice be continued unless
experience indicates that some other interval
is more appropriate.
Readout accuracy is directly proportional to
change in barometric pressure (i.e., a change
in cell pressure of 10 mm of mercury will
result in a readout error of approximately 1%
of reading). Therefore, if barometric pressure
changes significantly, it is advisable to
recheck the calibration against an upscale
standard gas.
4-3 SHUTDOWN
The Model 890 will retain settings during
prolonged shutdown. Recalibrate the
instrument upon restart.
4-4 DETECTION SYSTEM THEORY
The single-cell, multiple-wavelength
"Transflectance" measurement bench
provides a number of unique advantages over
conventional ultraviolet photometers.
Increased radiation transmission at the
measurement, reference and interferent
compensation wavelengths provides 4 to 5
times the energy transmitted in conventional
benches employing optical filters. This
increase yields an extremely stable, sensitive
and drift-free analysis.
The Model 890 employs a pulsed UV lamp
with peak wavelength generation from 225 to
650 nanometers. The pulsed lamp eliminates
the requirement for a mechanical chopper and
the attendant noise and stability problems.
Additionally, this pulsing action (50% duty
cycle) enhances the source life.
Next, a collimating mirror is used to focus and
direct the pulsed UV energy. Just prior to
entering the sample cell, a planar, nonposition-sensitive beam splitter is utilized to
direct 50 percent of the transmitted energy to
the first detector block assembly.
In the detector block, transflective mirrors with
selective wavelength reflection characteristics
are used instead of optical filters. These
mirrors further isolate the radiation into the
required measurement and reference
wavelengths, and reflect it onto a matched set
of silicon photodiode detector assemblies.
A second detector block, located just after the
sample cell, is an exact duplicate of the first.
This dual detector array allows the signal
processing circuitry to yield a highly sensitive
and accurate SO2 analysis.
Additionally, utilizing this same technique on a
second set of adjacent wavelengths, allows
accurate measurement and elimination of the
effects of absorption by interferent gas or
gases such as nitrogen dioxide.

(analyzer with the Calibration Gas Control
Option) and span the analyzer. If the Run
Mode value is not between 51% and
100% of the span gas value (while
keeping the span potentiometer between
5% and 95%), then the digital GAIN must
be adjusted. (The ideal span
potentiometer setting is 50%.) Note the

The GAIN may be changed to 1, 2, 4, 8,
or 16. If the span potentiometer status
(PS) was at the top of its range in Step 2
(95%), then the GAIN should be raised. If
the span potentiometer status (PS) was at
the bottom of its range in Step 2 (5%), the
GAIN should be lowered.
Additionally, the HIGH/LOW gain setting
may be toggled to achieve an
approximate 10:1 ratio.
5. Press SHIFT/ENTER to return to the Run

5-6 ERL ERROR MESSAGE
The error message, ERL, indicates one of two
events has occurred:
1. An improper linearization coefficient has
been inputted, thereby causing a
calculation loop error. This message is
only displayed in the Run Mode, and
since the calculation is generally executed
in Range Mode or the linearizer setup
screens, the user will not see the ERL
message until the analyzer is returned to
the Run Mode.
2. If the user enters a CAL GAS value that is
larger than the fullscale value, the ERL
message may be displayed. In such an
instance, the software attempts to
calculate a percent-of-fullscale value
which is higher than fullscale.
NOTE
The ERL message occurs only in extreme
cases, i.e., FS value = 5 ppm and CAL GAS
= 5000 ppm. If the user inputs, for example, 50 ppm on a fullscale of 5 ppm, the
ERL message will not appear. But when
the user attempts to span the range with
this value, the ER# [SPAN POT LMTS] error message will appear instead.
Rosemount Analytical Inc.
A Division of Emerson Process Management
To correct this condition, do the following:
1. The user should cross-reference the
linearizer coefficients entered with those
provided by the factory (or those the user
has calculated). Re-enter them properly.
Exit into the Run Mode, and the ERL
message should disappear.
2. If the coefficients are correct, then check
the fullscale/CAL GAS value relationship
in the Range setup screens. Correct this
condition, exit the Range setup screen,
and once the calculation has been
automatically redone, the ERL message
will disappear.
NOTE
The linearization calculation loop normally
takes from 2 to 3 seconds to perform its
task. If either of the two events described
above occur, though, causing a calculation
loop error, "WAIT-CALCULATING" may be
displayed for up to 20 seconds before it
exits with the ERL error message.
Also, when the ERL message is flashing in
the Run Mode screen, if the STATUS key is
pressed, the message [EL-LIN.COEFF
ERR] will be displayed briefly.

Realignment
After replacing the UV lamp, three items
associated with the optical bench must be
adjusted: Lamp, beam alignment, and
iris. The procedure for these adjustments
follows:
1. See Figure 6-5 above. The lamp can
be moved vertically and horizontally
by adjusting the clamp rod (item F).
The lamp clamp (item G), secures the
position of the clamp rod once
alignment is done.
2. See Figure 6-3 on page 6-5. Loosen
the three screws securing the lamp
housing to the collector housing to
allow vertical adjustment of the lamp
housing.
4. Set the analyzer to Range 3, and the
gain to "1 low."
5. Enter DIAGNOSTICS mode, verify
that source current is 300 mA ±10 mA
and all power voltages are +5, +12,
+15 and -15V (each ±5%).
6. Display the "Sample A" screen (still in
DIAGNOSTICS mode). Adjust the
horizontal and vertical positions of the
lamp and lamp housing until a
maximum reading is displayed.
Secure the lamp clamp (Figure 6-5
above, item G) and tighten the three
lamp housing screws (Figure 6-5
above, item A).
3. Power up the analyzer for a minimum
of 15 minutes.

7. Refer to Figure 6-6 below. Loosen
the spring-loaded handle mounting
screws to allow for beam alignment
adjustments. Note the adjustment
mark on the block and beam
alignment housing.
8. Rotate the beam alignment housing to
obtain the maximum signal. (The
marks already present just show the
proper starting point.)
9. Display the Detector Signal screen in
DIAGNOSTICS mode, and adjust the
iris for 0 mV ±5 mV. The cap protects
the iris from accidental movement.
10. In RANGE mode, set the gain to "1
high" and repeat step 9 for 0 mV ±10
mV.
11. In DIAGNOSTICS mode, verify the
detector signals are the following (for
a new lamp):
Sample A = 5 V ±0.7 V
Sample B = Sample A ±200 mV
Reference A = 75 to 85% of Sample
B
Reference B = Reference A ±200 mV
12. Press SHIFT and ENTER to return to
RUN mode.
This concludes lamp alignment and
balance of the system.
Restore the original settings for the
ranges and calibrate the analyzer.

6-3 CLEANING OPTICAL COMPONENTS
b.
The procedure for cleaning the beam
splitter and focusing mirrors is the same
as Section 6-3a above except: Under no
circumstances should the surfaces be
rubbed. These surfaces are very fragile
and easily damaged by mechanical
cleaning, degrading the performance of
the component. Cleaning must be
accomplished chemically.
The Model 890 contains several types of
optical and glass surfaces. Those should
never be touched, even when the components
requires cleaning. When handling these
components, always wear powder-free latex
gloves or finger cots, and hold them only by
the edges. NEVER BREATH ON THE
SURFACE AS A METHOD OF CLEANING.
To ensure an optical component is actually
clean, hold the surface to reflect light. If the
surface appears clean, it probably is.
c.
Spectrally Selective Mirrors
Each of these mirrors has a small dot on
the un-coated side. Do not remove this
dot.
To clean, carefully wet the entire mirror
with cleaning fluid, rinse with deionized
water while still wet, and blow dry with
clean, dry nitrogen or dry, oil-free air.
Source Envelope
The source envelope may be cleaned
with cleaning fluid and rinsed with
deionized water, and may be rubbed with
optical cleaning tissue if necessary. After
cleaning, rinse the lamp with alcohol and
deionized water, and blow dry with
nitrogen or dry, oil-free air.
After an optical component has been cleaned,
immediately install it into its holder to avoid
damage or contamination. If an optic must be
stored, do so in clean optical cleaning paper.
a.
Beam Splitter/Focusing Mirrors
d.
End Caps
Clean the sample cell end caps in the
same manner as the spectrally selective
mirrors (Section 6-3a above). After
cleaning, heat the end caps (with a heat
source such as a heat gun) to ensure that
no moisture remains trapped after reassembly.
If after repeated attempts, the mirror still
appears contaminated, wet the mirror with
cleaning fluid, and gently rub with a clean
wet optical cleaning tissue. Rinse and
blow dry. Repeat if necessary.

7-2 CIRCUIT BOARD REPLACEMENT POLICY
In most situations involving a malfunction of a
circuit board, it is more practical to replace the
board than to attempt isolation and
replacement of the individual component. The
cost of test and replacement will exceed the
cost of a rebuilt assembly. As standard policy,
rebuilt boards are available on an exchange
basis.
Because of the exchange policy covering
circuit boards the following list does not
include individual electronic components. If
circumstances necessitate replacement of an
individual component, which can be identified
by inspection or from the schematic diagrams,
obtain the replacement component from a
local source of supply.

7-4 LAMP REPLACEMENT
The ultraviolet lamp is a consumable part that
has an average lifetime of 6 months. When
the lamp reaches 50 % intensity, it should be
replaced. See Figure 7-3 on page 7-5 for a
lamp life vs. intensity chart.
The user can access all setup screens,
including the Diagnostics screen. When the
error condition is corrected (generally by
replacing the lamp (see Section 6-2 on page
6-3), the unit returns to normal operation.
The instrument's software monitors the UV
lamp source current during power-up and
every five minutes during normal operation. If
for any reason, including lamp failure, the
source current falls below a preset value, the
[UV LAMP ERROR] message will appear on
the display.
