Operator Messages / Fault Flags
Various messages can appear on the LCD screen to
indicate instrument status.
‘SAMPLE’
This indicates that the pump is running and the instrument
is sampling.
‘OFF’
This indicates that the instrument is about to switch off.
This command can be cancelled by a single press of any
button.
‘SAMPLE FAULT’
This indicates a problem with the instrument’s flow due
to the sample path being blocked, water ingress, a blocked
filter or pump failure.
In Measure mode, the pump stops automatically. The
sample line, filters etc. should be checked for water ingress
or blockage and Button One
should then be pressed
to restart the pump.
‘CHECK ZERO’
This indicates that there may have been a zero shift due
to the presence of gas. Switch off the instrument and
switch on again in fresh air.
‘ZERO FAULT’
This indicates that the zero is outwith its calibration limits.
Switch the instrument off and then on again in fresh air.
