To use this feature an EC sensor simulator(Part N° 32304) must be used in place of the sensor.Select “Temp.” or “Gas” and press “Start”The software performs the check in several steps. It asksthe user to select different gas values and temperatureson the simulator. For each position, it applies differentanode voltages. For each position and voltage applied:1) it waits some time (typ 1 minute for a null current)2) it displays if the values measured are acceptable3) it displays the current and temperature measuredIf the current or the temperature is not acceptable, a solution may be the calibration ofthe "gas amplifier" or the "temperature amplifier". To do this, please contact your HachUltra representative first.This feature allows you to check the ability of the TCmeasurement board to measure a range of currents andtemperatures. To use this feature a TC sensor simulator(Part N° 29117) must be used in place of the sensor.Depending on the operation(s) to be performed, select“V2”, “V3”, “Temp” or “Select All” and press “Start”The software performs each check in several steps andasks the user to select different values on the simulator.For each position, it applies different anode voltages. Foreach position and voltage applied:1) it waits some time (typ 1 minute for a null current)2) it displays if the values measured are acceptable (OK)3) it displays the current and temperature values measuredIf the current or the temperature is not acceptable, a solution may be the calibration ofthe "gas amplifier" or the "temperature amplifier", in which case please contact yourHach Ultra representative.This feature will display the measured values for V2 andV3 along with the recommended values. It is advisable toput the sensor in continuous purge mode during thisoperation by pressing the Continuous purge button.If the measured and recommended values differ by al a r g e m a r g i n , p l e a s e c o n t a c t y o u r H a c h U l t r arepresentative for advice.
