BAT FLAG OPERATES AFTER SHORT TIME
ARE BATTERIES NEAR END OF LIFE?
Normal life from a set of good quality alkaline batteries is
in excess of 15 hours operation If pre-used or poor quality
batteries are used the battery life may be substantially
reduced.
ACTION: REPLACE BATTERIES WITH GOOD
QUALITY ALKALINE CELLS
IS TEMPERATURE BELOW FREEZING?
The operating performance of the batteries is given at
normal room temperature; although the batteries will
operate below freezing their operating time can be
substantially reduced.
Keep spare batteries at room temperature for a few hours
if
you are using the instrument below freezing.
ACTION: KEEP A SET OF SPARE BATTERIES IN
THE HEATED VAN CAB RATHER THAN
IN THE UNHEATED SECTION IN COLD
WEATHER CONDITIONS.
ARE FILTERS BLOCKED OR SAMPLE FLAG
ACTIVATED?
If the batteries are poor quality or are nearly at the end of
their life, then a restriction or blockage on the sample line
causing increased pump load may cause battery voltage
to decrease, giving BAT flag after short period.
ACTION: REPLACE BATTERIES WITH FOUR NEW
LR20 ALKALINE CELLS
