8.3 Self-test Warning Messages
The following warnings may be displayed during the self-test period when the instrument is
switched ON.
Warning Description
Check Memory The instrument only has space to store less than 50 readings
before it is full. The exact number can be checked using the
‘View Readings’ option.
Memory Full There is no more space in memory to store readings. Both the
store and log options will be disabled until the memory is
cleared. The readings should be downloaded to PC using the
optional download software before memory is cleared.
Battery Low The instrument does not have enough power to operate for a full
day. The instrument should be recharged or connected to an
external power supply.
Service Due It has been 12 months (or more) since the instrument was
returned to the manufacturer for a service. The performance and
accuracy of the instrument may be impaired.
Low Flow The instrument’s gas inlet (or outlet) may be blocked. This
warning is most commonly caused by a water-logged or dirty
sample filter. Change the sample filter and check for obvious
blockages in the sample tubes. Alternatively, a small amount of
adjustment can be made to the low flow detection point to
compensate for minor changes in the performance of the pump
fitted to the instrument.
