9.7.5
O2 cell setup (by factory only)
If there is no calibration gas available and the cell must be replaced, this function permits changing a cell without calibration. This
can only be done if the cell factors have been measured at MRU and delivered together with the spare sensor.

1)
O2 cell setup requires input (edit function) of O2 factor and O2 offset values delivered with the spare sensor
2)
Temperature compensation of 20.9 % O

is required when oxygen value at air is changed too much because of gas or
flange temperature change. The difference of air oxygen measurement at lower temperature to measurement at higher tempera-
ture will be edit as “Temp.offs” value.
NOTE:
This procedure should be followed by new calibration using calibration gas cylinder.
Only authorized persons or manufacturer’s trained technicians are authorized to perform adjustments on the OMS420.
9.7.6
CO cell setup (by factory only)
If there is no calibration gas available and the cell must be replaced, this function permits changing a cell without calibration. This
can only be done if the cell factors have been measured at MRU and delivered together with the spare sensor.

CO cell setup factor and CO offset setup factor will be edit using the values delivered together with the spare sensor.
Set point of heat resistor [Ohm] must be also carried out according to § 6.7.12
NOTE:
This procedure should be followed by new calibration using calibration gas cylinder.
Only authorized persons or manufacturers trained staff are allowed to perform adjustments on the OMS420!
