The enclosure material is polypropylene and must not be exposed to
environments which are liable to result in mechanical or thermal
degradation or to damage caused by contact with aggressive substances.
Additional protection may be required in environments where the
instrument enclosure is liable to damage.
OPERATOR MESSAGES / FAULT FLAGS
Various messages can appear on the LCD screen to indicate instrument
status.
SAMPLE
Indication that the pump is running and the instrument is
sampling.
OFF
Indication that the instrument is about to switch off. This command
can be cancelled by a single press of any button.
SAMPLE FAULT
Indication of a problem with the instruments 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
Indication 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
Indication that the zero is outwith its calibration limits.
Switch the instrument off and then on again in fresh air. If the fault does
not clear, return the instrument for servicing.
BAT
Indication that the batteries will soon require replacement. At
this point there will be approximately 60 minutes left in a set of alkaline
batteries, although this figure will vary depending on battery
manufacturer, temperature conditions, usage etc.
With rechargeable batteries the BAT flag indicates approximately 30
minutes operation left.
As the battery power continues to fall, the LCD flashes a BAT FAULT
message. Subsequently the LCD displays OFF and the instrument
automatically switches off.
The batteries should be replaced immediately.
BAT FAULT
Indication that the batteries should be replaced
immediately.

data error has been detected. The instrument should be returned for
