4.5.2 Zero Fault
A “ZERO FAULT” warning and a flashing spanner symbol
appears after warm-up if the instrument is switched on in the
presence of gas or the instrument has been unable to zero
all sensors correctly.
The screen backlighting illuminates red, the audible alarm
sounds once every 2 seconds and the red LED’s flash.
It is strongly recommended the instrument is returned
to a gas free area. Switch the instrument OFF and then
switch ON again in fresh air. If the fault persists, return the
instrument to a GMI approved Service / Repair facility.
The instrument can however still be used to detect and alarm
on the other sensor(s) fitted. Press the Right Hand (RH)
button , as per the screen prompt, to continue.
