Sensors
----
If the analyser displays „-----" as CO
2
or CO reading, purge the sensors for at
least 15 minutes with fresh air. If the analyser still displays „-----" after repeated
calibration, the corresponding sensor must be replaced.
If CO-sensor has been overstressed with more than 2000 ppm, purge the
sensor with fresh air.
The analyser can also display „-----" if the batteries capacity is low. Replace the
batteries or operate your analyser via the adapter.
-OC-
-O>-
The analyser displays „-OC-„ or „-0>-„ if the reading exceeds or is below the
acceptable range.
The same applies if the temperature probe is not connected, a sensor has not
been successfully calibrated or a calculated value is not within acceptable
range.
Check that the temperature probe is connected correctly.
O
2
, CO or
pressure
readings are
not correct
or „zero“
Check the probe from the end of the probe up to the analyser plug-in for leaks.
Take care that the o-ring on the water trap filter is placed correctly and is not
damaged.
Check if the particle filter is wet, its orientation is correct as well as if o-ring and
the rubber stopper are positioned properly.
Check if the gas plug is connected to the analyser’s correct socket.
No printout: If the thermoprinter prints, but the paper is blank, check if the paper has been
put into the printer the wrong way round. Remove the roll and turn it over.
Also check printer‘s batteries.
No
response:
Analyser does not respond and can not be switched off: perform a „Reset" by
switching off the power supply, i. e. removing the batteries resp. rechargeable
batteries and/or the charger shortly (2 min) and then reconnecting them. Please
check time and date afterwards and correct them if necessary.
Service: Always return your analyser for service or repairs together with all connecting
cables, probes, factory control report , detailed description of the problem and
the invoice to your supplier.
