11.1.4 Gas/Temperature
(EC sensor process)
11.1.5 Gas/Temperature (TC sensor process)
11.1.6 Amplifiers (TC sensor only)
This feature allows you to check the ability of the EC
measurement board to measure a range of currents and
temperatures. 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 asks
the user to select different gas values and temperatures
on the simulator. For each position, it applies different
anode 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 acceptable
3) it displays the current and temperature measured
If the current or the temperature is not acceptable, a solution may be the calibration of
the "gas amplifier" or the "temperature amplifier". To do this, please contact your Hach
Ultra representative first.
This feature allows you to check the ability of the TC
measurement board to measure a range of currents and
temperatures. 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 and
asks the user to select different values on the simulator.
For each position, it applies different anode 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 acceptable (OK)
3) it displays the current and temperature values measured
If the current or the temperature is not acceptable, a solution may be the calibration of
the "gas amplifier" or the "temperature amplifier", in which case please contact your
Hach Ultra representative.
This feature will display the measured values for V2 and
V3 along with the recommended values. It is advisable to
put the sensor in continuous purge mode during this
operation by pressing the
Continuous purge
button.
If the measured and recommended values differ by a
l 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 a
representative for advice.
