INSTRUMENT STARTS CORRECTLY BUT
SWITCHES OFF WHEN PUMP OPERATED
IS TEMPERATURE LOW?
If the temperature Is low the battery capacity may be
reduced and the pump current increased, thus causing
battery voltage to be reduced below the automatic
shutdown level when the pump is switched ON.
ACTION: REPLACE BATTERIES WITH NEW
CELLS THAT HAVE BEEN STORED AT
AMBIENT TEMPERATURE THEN TRY
SEQUENCE AGAIN.
ARE SAMPLE LINE AND FILTERS CLEAR?
Low batteries used in low temperatures with a blocked
sample line or filters, may reduce battery voltage below
the automatic switch off point, thus causing the instrument
to switch OFF.
ACTION: CHECK SAMPLE LINE AND FILTERS
FOR BLOCKAGE.
HAVE NEW BATTERIES BEEN FITTED?
If the batteries are below capacity or they are not of good
quality, then they may reduce in voltage when the pump is
operated, thus switching the instrument OFF.
ACTION: REPLACE BATTERIES WITH GOOD
QUALITY LR20 ALKALINE CELLS.
ARE LR20 ALKALINE BATTERIES USED?
Only LR20 Alkaline cells will give the specified performance
ACTION: REPLACE ALL BATTERIES WITH NEW
ALKALINE LR20 CELLS.
