8.0 Problem Solving
This section outlines various warning and error messages which the
operator may receive during general operation of the instrument. For
further assistance please contact your nearest Bacharach Service
Center.
8.1 Warnings and Errors
When switched on, the instrument will perform a predetermined
self-test sequence taking approximately 60 seconds. During this
time many of the instrument’s working parameters and settings are
checked.
If any operational parameters are out of specifi cation or if the pre-
programmed recommended calibration / service date has passed,
errors or warnings may be displayed.
Use the “SCROLL UP” and “SCROLL DOWN” keys to move through
the list if required.
There are two types of warning that may be displayed:
• General warnings that may not affect the instrument’s function and
those where the self-test has detected a function that is outside of
the usual operating criteria, e.g. battery charge low, memory nearly
full.
• Operational parameters that could affect the performance of the
instrument, e.g. CO
2
out of calibration.
The most likely reason for these errors is either an incorrect user
calibration, or may indicate sensor failure. If an incorrect user
calibration has caused the warning it should be correctable by the way
of returning the instrument to factory settings, zeroing or carrying out a
user calibration as necessary for the relevant function.
