5.2 Manual Zero Point
•
The zero-point is factory-set; therefore zero calibration is not necessary.
5.3 Gain
•
Connect calibration adapter carefully to the sensor element.
•
Apply calibration test gas O
2
(150 ml/min; 1 Bar (14.5 psi) ± 10%).
•
Wait two minutes until the signal is stable, adjust control voltage with potentiometer ”Gain” until the signal
corresponds to the calculated value ± 2 mV, see “Calculation of Control Voltage”.
•
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 replaced.
Calculation of Control Voltage
Signal start 2 V / 4 mA
Control voltage (mV) = 160 (mV) x test gas concentration O
