OPERATING INSTRUCTIONS
1.
Turn the instrument on by rotating the thumbwheel downward in a
non-contaminated environment (fresh air).
2.
The green power LED will be illuminated when the unit is turned on.
If the battery level is low, the red LED will be steady and the tic will
not be adjustable. The battery will need replacing.
3.
Adjust to slow uniform tic rate with the use of the thumbwheel
(approximately two tics per second). This sets the instrument to the
background level. Start your testing by setting the instrument in fresh
air. The red LED indicator will flash in correspondence with the tic
rate. Allow about 10 seconds for the sensor to stabilize indicated by a
steady tic rate. (It may require up to two minutes to stabilize).
4.
The unit responds to gas with a variable audible tic sound. The
audible tic increases in volume when exposed to gases with 50
parts per million or more. When gas is detected, the tic rate will
increase, rotate the thumbwheel back to the steady tic, resetting
the instrument to this new background level. Move the instrument
into higher concentrations of gas (indicated by increase tic rate)
until the leak is found.
5.
The “Tip-Light” is used to see around the area of the leak in a dark
environment.
6.
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 side of the unit, if there
is high background noise or the operator does not want to disturb
other people. This also disables the speaker.
7.
If the tic rate becomes uncontrollable, it may be necessary to
change the sensor.
8.
The detector will respond to some leak finding solution (soap), so
use your detector first. If over exposed to some gases, the detector
may take an extended period of time to return to normal.
