11 Warning and error display
When switched on the instrument will perform a pre-determined self-test sequence taking
approximately 15 seconds. During this time many of the instrument’s working parameters
and settings are checked.
If any operational parameters are out of specification or 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. Only three warnings/errors can be displayed at any time.
To ascertain if more errors have occurred use ‘Key 8’ – Scroll down’ and ‘Key 2’ - Scroll
up’ through the list.
Warnings displayed:
All warnings displayed will be prefixed by the word WARNING followed by a relevant
description.
There are two types of warning that may be displayed:
1. General warnings that may not affect the instrument’s function and those where the
self-test has detected a function that is outside the usual programmed operating
criteria, e.g. battery charge low, memory nearly full.
2. Operational parameters that could affect the performance of the analyzer: Cell out
of calibration, CH4 out of calibration, CO2 out of calibration.
The most likely reason for the errors is either an incorrect user calibration or sensor
failure. If an incorrect user calibration has caused the warning it should be correctable by
