The pump has exceeded its recommended run-time and should
be changed. The instrument will need to be returned to the
manufacturer for service.
The Lithium Ion battery has exceeded its recommended life-time
or number of charge cycles and should be changed. The
instrument will need to be returned to the manufacturer for
service.
It has been over a month since the instrument was last user
calibrated. For optimal performance and accuracy it is
recommended that the instrument is user calibrated each time it
is used.
The instrument has an invalid time. This is most likely to occur
after a reset. The correct time should be entered using the set
‘Time & Date’ option via the ‘Utilities’ menu.
The instrument has an invalid date. This is most likely to occur
after a reset. The correct date should be entered using the set
‘Time & Date’ option via the ‘Utilities’ menu.
The instrument has detected a fault with the barometric sensor
or its calibration. This will have an effect on the accuracy of the
readings as they are pressure compensated. The instrument will
need to be returned to the manufacturer for service.
Note: *Certain configuration problems can be corrected remotely. Using the Analyzer
Data Manager software, it is possible to export the current configuration and e-
mail it to the manufacturer’s Technical Support or Service Department.
Depending on the type of error it may be possible to correct the configuration file
and import it back into the instrument.
8.4 User Calibration Trouble Shooting
A possible reason for this is because the instrument is trying to
zero to a level which is outside the predetermined range set when
the unit was calibrated at the factory or; the gas is not stable i.e.
is still flushing the measure gas or is using ambient air/gas that is
varying in concentration. To rectify this, first ensure the unit
contains absolutely none of the gas which is being zeroed by
flushing thoroughly with nitrogen. If it will not zero, then refer to
the instructions given in the ‘Factory Settings’ section. If the
instrument continues to fail to zero then the unit must be returned
to the manufacturer for investigation.
Check the span target is set to the correct value, if not, correct
and retry spanning the channel. Repeat the entire procedure,
including zeroing the channel and then calibrate the span. Ensure
the reading is stable before spanning the channel.
