10.0 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 Technical Support at
QED at +1 (734) 995-2547 or email service@qedenv.com.
10.1 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, CH
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 way of
returning the instrument to factory settings, zeroing or carrying out a user calibration as
necessary for the relevant function.
