When the unit detects a leak source an audible tone will sound and visual
indicators will light on the LED leak indicator display, appearing from left
to right; green to orange to red (red being the highest concentration, green
the lowest). Increasing levels indicates the proximity of the leak location
is getting closer. When the unit signals a leakage, pull the probe away
from the leak for a moment and then bring it back slowly to pinpoint the
location. If the combustible leak is large setting the sensitivity switch to
LOW (see sensitivity adjustment) will make it easier to nd the exact site
of the leak. Return the sensitivity switch to HIGH before searching for any
additional leaks. When you’ve nished testing for leaks turn the unit OFF
and store it in a cool, dry, clean place to protect the sensor and unit from
any possible damage.
Ambient Concentration Reset
This combustible leak detector features an ambient concentration reset
function that sets the unit sensors to ignore the ambient gas concentrations
presented. When turned ON the unit’s sensor will set the level of present
combustible gas to zero. Only a concentration greater than what is initially
registered will cause the unit to alarm. Resetting the unit by pressing the ON
OFF
button during measurement resets the ambient concentration allowing the
unit to pinpoint the source of the leak allowing it to register higher concen-
trations. Resetting the unit with no combustibles present causes any read-
ing above zero to be detected. To do this simply move the unit to a location
that has clean and fresh air, such as outdoors and press the ON
OFF button.
CAUTION
Be aware that this feature will cause the unit to ignore any combustible
present when powered ON. If the unit sensor is pointing towards a leak
when you turn the unit ON the alarm will not sound
Sensitivity Adjustment
This unit provides two levels of sensitivity. When the unit is switched
ON it is set to high sensitivity by default. To change the sensitivity, press
the Lo
Sensitivity button. The two left green LED’s will then ash indicating low
sensitivity has been selected. To switch the unit back to high sensitivity,
press the
Hi
Sensitivity button. The two right red LED’s will then ash indicating
that high sensitivity has been selected.
