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 Technical
Support at VIASENSOR at +1 (909) 783-9472 Ext. 7130.
8.1 Warnings and Errors
When switched on the instrument will perform a predetermined 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 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 the usual operating criteria, e.g.
battery charge low, memory nearly full.
• Operational parameters that could affect the performance of the instrument, e.g. N
2
O
out of calibration.
The most likely reason for these errors is either an incorrect user calibration or they may
indicate 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.
Under and Over Range Codes
If a reading is over range (i.e. above the maximum allowed reading) it will be displayed
with more than chevrons (>>.>). This can occur if a channel has been incorrectly
calibrated or the sample gas has exceeded its specified range (e.g. N
2
O > 20%).
If a reading is under range (i.e. below zero) it will be displayed with less than chevrons
(<<. <). Refer to section ‘7.0 Calibration’ of this manual to remedy under-range by
performing a user zero.
A number displayed as asterisks (**.*) indicates an error, usually where the instrument has
been unable to complete a particular calculation. Typically, this will be the first indication of
a fault condition.
Where no data is available dashes (--.-) are displayed. This usually occurs when a
particular reading or parameter has been skipped by the user, or where an optional
accessory is not fitted correctly, i.e. a temperature probe.
8.2 Battery No Charge Reset
Should the instrument completely run out of charge (so low that memory is lost), upon
recharging, the instrument will force the operator to re-enter the time and date parameters.
No other data is lost.
