PIPING AND WIRING
2.1 Piping
Piping methods depend on the application, select the appropriate system configuration, and install
pipes accordingly following examples.
2.1.1 System Using Open Head Tank and Zero Turbidity Filter
This is a typical system. A piping diagram is shown in Figure 2.1. Air bubbles in a water sample are
removed by an open head tank and the water sample is introduced into the detector at a stable flow
rate.

Piping Diagram
• To prevent corrosion of water inside the zero turbidity filter, allow water to flow through the filter
and flow out from the zero water drain valve continuously at a flow rate of approximately 10 ml/
min.
• When using filtered water as zero reference, install a filter with the appropriate pore size
depending on the measuring range.
Measuring range of less than 2 NTU:
0.2 µm
Measuring range of 2 NTU or greater:
1 µm

<2. PIPING AND WIRING>
2.1.2 System without Head Tank and Zero Turbidity Filter
This is a simple system where a water sample is taken from the process and directly introduced
into the detector. This system configuration can be used when a water sample contains a negligible
amount of air bubbles or when the turbidity of a water sample is high and the effect of air bubbles is
nonsignificant.
CAUTION
Sample water conditions and ambient temperature must meet the specifications: maximum pressure:
500 kPa; sample temperature: 0 to 50°C; ambient temperature: -5 to 50°C.

<3. OPERATION>
3.2
Normal Operation
The TB750G turbidimeter does not normally require any manual operations except when periodic
cleaning/calibration is performed or when a failure occurs.
3.2.1 When Sample Water Supply is Cut Off
The turbidity measurement is not affected by temporary suspension of sample water supply, but longterm suspension may interfere with the accuracy of the instrument. Since the TB750G cannot detect
whether the sample water supply is stopped or not, periodical check of the sample line is needed.
3.2.2 Shutdown
The parameter settings and other information set in the turbidimeter are retained even if power is
turned off. If the instrument will be out of operation for a long period, power should be removed.
Dirt and/or stains on the instrument should be washed off thoroughly when the turbidimeter is to be
removed from the site. Rinse the inside of the measurement cell, and then empty the cell or keep zero
water running through the cell.
3.2.3 Restart
When power is returned, the turbidimeter is put into the measurement state. It requires at least one
hour for warm-up. Check that the reading stabilizes well, before performing calibration.

based on sensitivity correction factor (K)=1 and zero correction factor (B)=0. (Value not affected by

*2: Span calibration in {STD.CAL} is performed using turbidity standards or check block that has been
selected in CODE16.
*3: In zero calibration, calibration value should be “0.000” and cannot be changed. Only [ENT] key is
accepted to confirm.
*4: In span calibration using check block, calibration value cannot be changed. Only [ENT] key is
accepted to confirm.
*5: First determine the decimal point using [>] key and then set value in the range of 0.000 to 20000 NTU.
*6: Pressing [ENT] key during self-adjustment will abort the procedure, and the turbidity when [ENT] key
is pressed will be used for calibration factor calculation.
*7: Only [YES] key is accepted to confirm.
Note: Calibration factor will be updated when the calibration procedure is completed without cancellation
or errors. If [YES]/[NO] key is pressed on error code display, the instrument goes to {CALIB} display.
Error E203 or E204 appears after the instrument once returns to measurement display.

Lamp Replacement
CAUTION
Wait for some time to replace lamp assembly because lamp temperature is high just after lamp power
was turned off.
Although the lamp has a normal service life of more than one year, it is recommended that the lamp
be replaced at an interval of one year in terms of preventive maintenance. Some lamps may fail within
one year.
The following describes how to replace the lamp.
(1) Remove power from the TB750G turbidimeter.
(2) Remove the cover of the light source unit on the left side of the detector by loosening the 4
setscrews.
(3) Disconnect the terminals for lamp from the terminal block. Remove the lamp assembly by
loosening the 2 setscrews.
(4) Replace the lamp assembly with a new one. Mount the new lamp assembly with the 2
setscrews. Connect the terminals for lamp to the terminal block (LAMP).
(5) Supply power to the TB750G turbidimeter.
(6) Check that the lamp is lit. Replace and fix the cover of the light source unit by tightening the 4
setscrews.
(7) After the lamp replacement, allow the turbidimeter to warm up for at least one hour. Then,
perform calibrations instructed in Sections 3.
(8) Lamp replacement is now complete.

Calibration Methods
(1) Select when performing a calibration using 0.2 or 1.0 µm filtered water as zero reference.
(2) Select when performing a 2-point calibration using standard solutions. Use this method to
perform a calibration complying with EPA 180.1.
(3) Select when performing a zero point or sensitivity correction after calibration (1) or (2). This
method is used to adjust the meter reading to reflect the lab data in a grab sample calibration.
Note: The instrument has been pre-calibrated using 0.2 µm filtered water as zero reference at the
factory before shipment.
5.2.2 2-point Calibration Using Turbidity Standard Solutions
A 2-point calibration of the TB750G is performed with turbidity standard solutions equivalent to zero
solution and to span solution. After accepting both zero and span values, the meter calculates a
calibration factor.
When user-prepared zero and span solutions are used for calibrations, the turbidity of diluting water
for calibration should be measured with a calibrated lab turbidimeter in advance. Prepare a formazin
standard solution as a span solution. If the turbidity of diluting water is high against the measurement
accuracy, add the turbidity of diluting water to the nominal turbidity of the prepared formazin standard
solution. Use diluting water as zero solution and a formazin solution as span solution for the
calibration.
Refer to Section 3, “Operation” for concrete operating procedures.
