To pin-point a gas leak:
After completing the warm up period in
fresh air,
move the tip of the
GLD/450plus’s “wand” towards the suspected gas leak. The rate of
bleeping and LED flashing will increase as the concentration of the gas
increases, thereby leading you to the gas leak.
If the Red LED is illuminated and the bleeping is continuous before you
have pin-pointed the gas leak, you must reset the GLD/450plus in this
concentration of gas. To do this switch the GLD/450plus OFF, then back
ON and wait for 20 seconds to allow the sensor to reset itself in this
concentration of gas. You can then continue to pin-point the gas leak.
Tips:
If the initial bleep rate does not settle to about twice a second, switch off
and back on to allow additional re-setting time.
The unit may be reset at any time by switching off and back on.
The unit will detect methane and most other "HC" gases down to low
ppm levels.
The unit will respond to some leak detection fluids. Use the
GLD/450plus first!
The unit is intended for use in sheltered areas or indoors as severe
draughts may cause (temporary) false indication.
Avoid contamination by water or dirt and do not allow any reactive
chemicals etc. to come in to contact with the sensor.
