Be sure to observe the following precautions when you operate it. Handling Precautions • Installation location The OX400 is structurally non-explosion proof so you cannot use it in an explosive atmosphere. Also, see 3.1, “Installation Location.” • Power supply Be sure to check that the power supply voltage specification of the OX400 matches the voltage of the power supply before turning on the power. • Protective ground Be sure to connect the power plug of the OX400 to the 3P socket with a protective ground pin in order to prevent electric shock. • Fuse Be sure to use a designated fuse in order to prevent a fire. Be sure to turn off the power before replacing the fuse. Never use a fuse holder other than a designated one. IM 11M10B01-01E 6th Edition : May 19, 2017-00 iv • Removing cover There is a heated area inside the OX400, and touching it directly may cause a burn injury. Never remove the cover except to replace the sensor. • When opening the cover to replace the sensor, turn off the power switch, remove the power plug from the socket, and wait for 1.5 hours or more before opening the cover. • Before connecting wires to the terminal block on the rear panel of the OX400, remove the power plug from the socket in order to prevent electric shock. After finishing the wiring, secure the removed special terminal cover with screws. • The OX400 is a measuring instrument intended to be installed indoors, so do not install it in a location that is exposed to direct sunlight, rain, and wind. • Do not use the OX400 in a location that may be subject to vibrations and impact. Doing so may cause destruction and damage to the internal sensor. • Do not apply a pressure of 30 kPaG or more to the gas inlet. Doing so may cause destruction of the suction pump and damage to the sensor. Be sure to reduce the sample gas pressure to the atmospheric pressure level before introducing the gas. • Be sure to use metal piping for the gas piping; particularly when handling oxygen concentration in 1 vol % or less. Use of piping materials such as polyethylene, vinyl, rubber, and plastic may cause significant errors in measurements because of their large oxygen transmission and absorption rates. • The presence of corrosive gas components (H2S, SOx, HCl, NH3, HF, and the like) or potentially toxic elements (Si, Sn, Cd, Te, As, P, and the like) in the sample gas may cause deterioration of the sensor. Be sure to remove them with an activated carbon filter or the like in the previous step of the OX400 before introducing the gas. • The presence of combustible gas in the sample gas may cause errors in measurements because oxygen in the sample gas will be consumed by combustion. Be sure to remove it with a filter or the like in the step before introducing the sample gas into the OX400. • Make sure the temperature of the sample gas is 50°C or less. • Be careful because the presence of water droplets in the sample gas may cause damage to the sensor. • Keep the supply gas flow rate and pressure as constant as possible while introducing the gas. • Keep the sample gas outlet open to the atmosphere during operation. If a gas line must be used to discharge gas, use a gas line with a connector that has the largest possible diameter in order to prevent back pressure. • Do not use the supplied power cord with another device. • Power cable suffix codes of “-D” can be used in Japan, because another cable doesn’t conform to PSE marking. n Product Disposal The instrument should be disposed of in accordance with local and national legislation/regulations.

Installation 3.1 Installation Location 3-1 <3. Installation> The OX400 is a measuring instrument intended to be installed indoors. Install and operate it in a location that meets the following conditions in order to ensure the best performance. (1) Location where there is no corrosive gas. (2) Indoor location where there is no mechanical vibration. (3) Location that is not exposed to direct sunlight and radiant heat. (4) Location that is free of dust and dirt particles. (5) Location with a room temperature of 0 to 40°C and no condensation. WARNING Never use the OX400 in an explosion hazardous area. Doing so may cause a fire, explosion, or the like. • The OX400 is a measuring instrument intended to be used indoors. Do not install it in a location that is exposed to direct sunlight, wind, and rain. • Do not use the OX400 in a location that may be subject to vibrations and impact. Doing so may cause destruction and damage to the internal sensor. • Do not apply a pressure of 30 kPaG or more to the gas inlet. Doing so may cause destruction of the suction pump and damage to the sensor. Be sure to reduce the sample gas pressure to the atmospheric pressure level before introducing it. • Be sure to use metal piping for the gas piping; particularly when handling oxygen concentration in 1 vol % or less. Use of piping materials such as polyethylene, vinyl, rubber, and plastic may cause significant errors in measurements because of their large oxygen transmission and absorption rates. • The presence of corrosive gas components (H2S, SOx, HCl, NH3, HF, and the like) or potentially toxic elements (Si, Sn, Cd, Te, As, P, and the like) in the sample gas may cause deterioration of the sensor. Be sure to remove them with an activated carbon filter or the like in the previous step of the OX400 before introducing the gas. • The presence of combustible gas in the sample gas may cause errors in measurements because oxygen in the sample gas will be consumed by combustion. Be sure to remove it with a filter or the like in the previous step of introducing the sample gas into the OX400. • Make sure the temperature of the sample gas is 50°C or less. • Be careful because the presence of water droplets in the sample gas may cause damage to the sensor. • Keep the supply gas flow rate and pressure as constant as possible while introducing the gas. • Keep the sample gas outlet open to the atmosphere during operation. If a gas line must be used for discharge gas, use a gas line with a connector that has the largest possible diameter in order to prevent back pressure.

Install this equipment in an accessible location to facilitate maintenance. Maintenance conditions vary depending on the gas conditions. Replacement intervals for the filter and activated carbon should be determined in accordance with the operating conditions. • Activated carbon filter life is about 50 hours. (if measured gas contains isopropyl alcohol of concentration 500 ppm, and flow is 500 mL/min.) • In case of using the built-in pump or with the aspirator, the activated carbon filter life is about 25 hours. IM 11M10B01-01E 6th Edition : May 19, 2017-00  4-1 <4. Piping and Wiring> 4. Piping and Wiring 4.1 Piping Be sure to observe the following precautions when connecting the gas pipe to the OX400. (1) The connections for both the gas inlet and outlet are Rc1/4 or 1/4NPT. Use the specified thread and securely connect the gas pipe so that no leakage will occur. WARNING When screwing in the pipe, be sure to hold the inlet hexagonal part in place with a wrench or the like. Not doing so and using a strong force when screwing in the pipe may cause the thread on the OX400 to rotate, resulting in damage to the internal pipe. (2) With respect to piping, use a metal pipe. Use of materials such as plastic, vinyl, rubber, and the like may result in inaccurate measurements due to the transmission of oxygen from the air and absorption onto the inside surface of the pipe. Particularly with respect to silicon tube, be careful because due to its large oxygen transmission rate, accurate measurements cannot be performed in the low concentration range. (3) Be careful of leakage from the pipe because it may cause measurement errors. Particularly in the low concentration range, take great care because even though the pressure inside the pipe is positive, oxygen may flow from the air due to diffusion, resulting in a large error. (4) Fluctuations of back pressure at the pipe outlet may cause measurement errors, so always keep the pressure at the atmosphere pressure level as much as possible during operation.

Roughly three types of measurement range are available, “Auto Range,” “MANUAL Range,” and “Partial Range.” (1) Auto Range “AUto” (auto range) With respect to this range, the range is switched automatically depending on the oxygen concentration value. Enter range code “1” (default) if the full scale is always 10 x 10n, as in the case of 0 to 10 ppm, 0 to 100 ppm, 0 to 1000 ppm, 0 to 10%, 0 to 100%. Furthermore, enter range code () “2” to “9”, as in the case of 0 to 0 ppm, 0 to 00 ppm, 0 to 000 ppm, 0 to 0%. For example, enter range code “2” if 20 x 10n applies, as in the case of 0 to 20 ppm, 0 to 200 ppm, 0 to 2000 ppm, 0 to 2%, 0 to 20%. (2) MANUAL Range “MAn” (fixed range) This range is a fixed range. Select one from the following six ranges: 0 to 10 ppm, 0 to 100 ppm, 0 to 1000 ppm, 0 to 1%, 0 to 10%, and 0 to 100%. The range is always the same and is independent from the oxygen concentration. (3) Partial Range “FrEE”–“Fr.HI” –“Fr.Lo” (free range) With respect to this range, any range can be set and fixed. However, the smallest span of the range must be more than 20%FS of the above MANUAL range. Examples: 2 to 4 ppm if the MANUAL range is 0 to 10 ppm 60 to 80 ppm if the MANUAL range is 0 to 100 ppm NOTE: Flashing italic characters such as “1.000” used in the subsequent operation flow charts mean waiting for key input. Furthermore, the larger box means the main display (large digital display) on the front panel and the smaller box means the sub-display (small digital display).

Operation and Parameters> 6.1.8 Setting Output Smoothing “SMoo” If the oxygen concentration of sample gas rapidly changes, and the measured value is used for control, harmful results may occur such as frequent on and off switching. In such a case, signal changes can be smoothed by giving an appropriate time constant and performing calculation. Smoothing factor from 0 to 60 seconds can be set. When the output smoothing is set, the smoothed value is an instantaneous value, which is displayed and output in analog form. The smoothed value is also used as the instantaneous value for checking the concentration alarm and for RS232 communication. The output smoothing is “non“ 0 second by default.

Hold down the [MODE] key for 2 seconds to return to the beginning of the calibration “CAL” and press the [MODE] key again to return to the measurement state. With respect to the calibration methods of the OX400, there are four types of method. (1) 3-point (All) calibration “ALL” By performing calibration at the three points of 10 ppm, 1000 ppm, and Air, the linearity for the entire zone between 0-10 ppm and 100% O2 is guaranteed. Gas used for calibration is restricted to the ranges of O2 concentration as follows. (1) 8 ppm ≤10 ppm gas ≤ 20 ppm (2) 800 ppm ≤1000 ppm gas ≤ 2000 ppm (3) O2 concentration in Air: 20.6% (Normal air is within this range) Note: Be sure to use gas that meets conditions (1), (2), and (3) for calibration. (2) 2-point calibration “2Pnt” Select zero and span calibration points in the measurement range you will use to perform calibration. However, gas used for calibration is restricted to the ranges of O2 concentration as follows. (1) Zero gas is 8%FS or more. (2) Span gas is less than 120%FS. (3) Between zero and span of the smallest range must be more than 20%FS of the MANUAL range. Example 1: Two points of 1 ppm and 3 ppm in the 10 ppm range Example 2: Two points of 20 ppm and 40 ppm in the 100 ppm range < When the range is more than 1000 ppm.> (1) Zero gas is 800 ppm or more. (2) Span gas is 100%FS or less. (3) Between zero and span of the smallest range must be more than 2000 ppm. Example 3: Two points of 0.6% and 0.8% in the 1% range Example 4: Two points of 20.6% and 90% in the 100% range (3) 1-point calibration “1Pnt” Principally, 1-point calibration allows obtaining an accurate concentration in an area near the calibration point, but the error may become greater as the distance from the calibration point increases. This is a useful calibration method when it is used in some limited areas. Select one point in an area as close to the concentration you want to measure as possible to perform IM 11M10B01-01E 6th Edition : May 19, 2017-00  6-11 <6. Operation and Parameters> calibration. However, there are the following limits to the O2 concentration. Be sure to perform calibration in that range of the O2 concentration. O2 concentration limits: 0.9 ppm or more and 12% or less, or between 35% and 100%. (4) Air calibration “AIR” This is air-only calibration. Ues the cleanest air possible to perform calibration. Note: If you press the [MODE] key during calibration to exit the calibration mode, that calibration becomes invalid. If an error occurs during calibration, the ERR/ALM lamp turns on, and an error/alarm code is displayed on the sub-display. That calibration may become invalid depending on the error factor.

Gas outlet Rear panel of the OX400 Figure 6.18 Example of Connecting Aspirator and Gas Piping Figure 6.19 shows the relationship between the supply pressure, suction gas flow rate, and total discharge gas flow rate of the aspirator. The air supply pressure to the aspirator shall be in the range between 65 and 100 kPaG. Also, maintain the air supply pressure at a certain value to prevent the pressure from fluctuating. If the pressure fluctuates, the suction flow rate fluctuates resulting in a fluctuation of measured data. The allowable pressure fluctuation range is the set pressure ±2 kPaG. Furthermore, the outlet pressure shall be equal to the atmospheric pressure. Also make sure back pressure is not applied.

Inspection and Maintenance> Inspection and Maintenance Routine inspection and maintenance is important to ensure operation of the OX400 in a good condition. Perform regular inspection and maintenance in accordance with the following instructions. 7.1 Routine Inspection and Maintenance (1) Checking readings Measure calibration gas about once every two to three months and check the readings. If an error is found with the calibration gas concentration, perform zero-span calibration in the range you use. (2) Checking gas flow rate Regularly check the sensor gas flow rate in order to make sure that the flow rate is 200 ± 25 mL/ min (a floater should be between upper and lower bar of the 200 mL/min bar on flowmeter). (3) Other Regularly check for signs of malfunction such as strange noises of the pump and fan, or unusually high temperature of the case. (4) Replacing the fuse 7.2 Be sure to turn off the power of the OX400 and remove the power plug from the socket before replacing the fuse. The fuse is installed in the lower part of the power cord plug on the rear panel of the OX400 (see right figure). Remove the power cord from the plug, pull the fuse holder out of the lower part of the plug, replace Fuse the fuse with a new one, and push the fuse holder back in place. Be sure to replace the old fuse with a correctly rated one. If a replaced fuse burns out soon, the circuit is likely to be defective. Please contact our service department. Fuse Holder Inspection in the Event of an Error If an error occurs, the ERR/ALM lamp on the front panel turns on. An error/alarm code is displayed on the sub-display. If multiple errors occur, codes are displayed in the order of occurrence. An error means a malfunction, so the heater is turned off and the measurement is stopped. When an error occurs, repair is required. On the other hand, an alarm means a warning, so measurement is continued. An alarm occurring during calibration may invalidate the calibration depending on the content of the alarm. The following shows the display and output in the event of an error/alarm.
