high
System
error,
open
The error can only occur during an O
2
sensor calibration. An error reset can be carried
out by the user. A successful re-calibration also resets the error.
Possible causes:
defective false test gas (not applicable with test air), test gas flow too
low, O

Possible causes:
Incorrect calibration gas, test gas flow too low, probe filter damaged,
filter head missing, faulty O

Electronic temp. too low
Possible Cause:
The ambient temperature of the transmitter is lower than the specified
lower limit. The specified measurement tolerances are no longer guaranteed.
Electronic temp. too high
Possible Cause:
The ambient temperature of the transmitter is higher than the specified
upper limit. The specified measurement tolerances are no longer guaranteed.
Clock battery low
The alarm can only be reset by the user after replacing the clock battery (Lithium type
2032). As long as the system is connected to AC power, the alarm has no impact. Only
after restarting system will the time / date be incorrect. A possible timed automatic
calibration can no longer work correctly.
