Sensitivity adjustment finished, sensitivity offset saved
Current Value too small
No test gas or incorrect test gas at the sensor
Current value too high
Test gas concentration > entered value.
Internal error. Exchange gas sensor.
Test gas too small
Set test gas concentration must be within 30% and 90% of the
measuring range.
Test gas too high
Actual value unstable
Displayed as long as the deviation between two measuring cycles
(100 ms) is > 3%.
Goes out automatically when sensor signal becomes stable.
Time too short
●
Message “Actual value unstable” starts internal timer (10-20 s).
●
The text is displayed when the timer has expired and the actual
value is still unstable.
●
The process starts again.
●
If the value is stable, the actual value is displayed again and the
adjustment process is continued.
●
There is an internal error when the cycle repeats several times.
●
The adjustment procedure must be canceled and the gas sensor
