Operation

Turn the instrument on by rotating the thumbwheel downwards in a non-contaminated envi-
ronment. i.e. Fresh Air.
The green Power LED will be illuminated when the unit is turned on. If the battery level is
low then the red LED will be steady and the tic rate will not be adjustable. The battery will
need replacing.
Adjust to a slow uniform tic rate with the use of the thumbwheel (approximately 2 ticks per
second). This sets the instrument to the background level, you should start your testing by
setting in fresh air. The red LED indicator will flash in correspondence with the tic rate.
Please allow around 10 seconds for the sensor to stabilise indicated by a steady tic rate.
However it may occasionally require up to 2 minutes to stabilise under some conditions.
The unit responds to gas with a variable audible ticking sound. The audible tic increases in
volume when exposed to gases with 50 parts per million or more. When gas is detected the
tick rate will increase, rotate the thumbwheel back to the steady tick, resetting the instru-
ment to this new background level. Move the instrument into higher concentrations of gas
(indicated by increased tick rate) until the leak is found.
The 'Tip-light' is used to see around the area of the leak when in a dark environment.
When this instrument is used in noisy environments, look at the red LED which flashes
more rapidly as the tic rate increases. The optional earphone can be plugged into the unit's
side if there is high background noise or the operator does not want to disturb other people.
This also disables the speaker.
If the tic rate becomes uncontrollable, it may be necessary to change the sensor.
The detector will respond to some leak finding solution (e.g. Soap), so please use your de-
tector first. If over exposed to some gases, the detector may take an extended period of
time to return to normal.
