Cause
The instrument has detected a fault in the
IR sensor.
#118: IR-sensor faulty.
There is no valid zero-point calibration.
#106: Zero-point calibration was not completed
successfully (e.g. no suitable zero gas used/
CAT sensor was exposed to nitrogen).
#123: Fault during calibration
The instrument has detected a fault in a sensor.
#108: Inconsistent sensor data
#133: Measuring signal is outside of the
permitted range.
The CatEx sensor needs oxygen for correct
operation. If insufficient oxygen is available, the
sensor cannot measure correctly.
The date and/or time are set to invalid values.
The data logger is almost/completely full.
The warming-up times of the sensors may vary,
depending on the ambient conditions.
The measuring error is higher during the
warming-up phase. Calibration cannot yet be
executed.
The sensor no longer has sufficient reserves for
calibration.
The sensor is not supported by the instrument.
Remedy
Switch the instrument off and then on again,
or remove and reconnect the power pack.
Change IR-sensor if necessary. If the fault is still
displayed, contact DrägerService.
Repeat zero-point calibration with a suitable zero
gas.
Carry out zero-point calibration with a suitable
zero gas.
Repeat the calibration procedure or disconnect
and reconnect the power pack. If the fault still
exists, change the sensor or inform Dräger-
Service.
Switch the instrument off and then on again, or
remove and reconnect the power pack.
Change sensor, page 86 or inform
DrägerService.
Use an IR-Ex sensor in atmospheres with O
deficiency.
Set the date and time correctly.
Read out the contents of the data logger (with
the software Gas-Vision) and/or clear the data
logger (see page 61).
Wait until the sensor has warmed up.
Info Mode provides further details.
Measurements can still be carried out under
these conditions.
Replace the sensor in the near future.
The sensor cannot be used.
For details, contact DrägerService.
