Gain Calibration
Notes:
CO calibration gas is toxic, never inhale the gas!
Symptoms: Dizziness, headache and nausea.
Procedure if exposed: Take the victim into fresh air at once, call a doctor.
x
Open window SP 01 in menu “Measuring Value”.
x
Connect calibration adapter carefully to the sensor element.
x
Apply calibration test gas CO (300 ml/min; 1 Bar (14.5 psi) ± 10%).
x
Wait two minutes until the measuring value is stable, adjust the value with potentiometer ”Gain” until the value
corresponds to the Calibration gas concentration.
x
Remove calibration adapter with a careful light turn. Check the sensor for correct mounting!
By limiting the gain factor, calibration will not be possible any more when the sensitivity of the sensor
reaches a residual sensitivity of 30%. Then the sensor has to be replaces.

Exchange of Sensor Element
Consider static electricity! See point 3.
Sensor should always be installed without power applied:
x
Unplug old sensor element from the PCB.
x
Take the new sensor out of the original packing.
x
Plug in the sensor element into the PCB at X3/X7.
x
Calibrate according to section 8.
