OPERATION AND USE
NOTE: These instruments have cross sensitivities to a variety of
gases.
9. To assist in locating the source of small combustible gas leaks or
surveying areas outdoors or indoors, press and release the TICK/CAL
button (B). This will start an audible tick preset at 2-3 ticks per second.
Move the sensor toward the area suspected of leakage. As the sensor
moves closer to a leak source the tick will increase. When the tick
becomes a steady tone press the TICK/CAL button (B) again while
keeping the sensor head in the same position. This will slow down the
tick and allow the operator to find a higher concentration using the same
procedure.
If there is no tick, press the TICK/CAL button (B) again to reset to the
steady ticking sound. For best results always use the leak detector prior
to using any liquid leak detection fluids as these sensors will detect their
presence.
10. Following Country, Province, State, Municipal and/or Company
procedures move to the areas where gas readings are suspected or
must be tested. During sampling the respective readings may change.
Audible and visual alarms will activate when the preset limits are
reached.

button (C) to turn on the back light Press again to turn off.
