Operation

 Turn the instrument on by rotating the thumbwheel downwards in a non-contaminated
environment. 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
instrument to this new background level. Move the instrument into higher concentrations of
gas (indicated by increased tick rate) until the leak is found.
