Operating Instructions
Some environmental conditions may cause inaccurate readings such
as; high pollutant environments, large temperature variations, high wind
velocity, environments containing combustible gases, environments
containing organic solvents, adhesive vapors, fuel gases or vesicants.
Power ON/OFF & Concentration Reset
1. Press the ON
OFF button to turn the meter on. Press and hold the ON OFF
buttonforapproximately5secondstoturnthemeteroff.
2. When powering on, the LED leak indicators will continuously
illuminatewhilethesensorheatsupforapproximately2minutes.
3. When complete, the meter will emit 2 beeps conrming that it is
ready to use.
Auto Power Off
To preserve battery life, the meter is programmed to turn off after 10
minutes of inactivity.
Self-Test (Performance Check)
1. Turnthemeteronandsetthesensitivitylevelto"Hi".
2. Open the cover to the leak-check bottle and slowly move it closer to
sensor tip.
3. If the unit is in working condition the LED leak indicators will light up,
from low to high.
4. Repeat this process to conrm that the closeness of the leak-check
bottle results in the leak indicators to uctuate from low to high.

Measuring Procedure
It is recommended to position the tip of the sensor probe within 1/4 inch
(6mm)ofthesuspectedleaksource.Slowlymovethesensorprobepast
each possible leakage point.
Note: Fast movement of the sensor probe or blowing into the sensor tip
will affect the air ow over the sensor and cause the unit to alarm.
1.
When a leak is detected, an audible tone will sound and the LED
leakindicatorswilllightfromrighttoleft;green(lowconcentration)to
orange(mediumconcentration)tored(highconcentration).Increasing
levelsindicatesthattheproximityoftheleakisgettingcloser.
2. When the meter signals a leakage, pull the probe away from the leak
for a moment and then bring it back slowly to pinpoint the location.
Note:Iftheleakislarge,trysettingthesensitivityswitchtoLOW(see
"Sensitivity Adjustment" for details) as it will make it easier to pinpoint the
exactlocationoftheleak.
3. AlwaysreturnthesensitivityswitchtoHIGHbeforesearchingforany
additional leaks.
4. When a user is 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
continued...
This combustible leak detector features an ambient concentration reset
function(Zeroout)thatsetsthemeter'ssensortoignorethepresent
level of ambient gas concentrations. When the meter is initially powered
on it will recognize the background gas concentration as 0 by default.
Therefore, it is recommended to turn the meter on in an area with clean
and fresh air such as outdoors allowing the sensor to zero out in a
non-affected area. If a user presses the
ONON
OFFOFF
button while measuring, it
will reset the current background gas concentration to zero again. This
function is designed to allow the user to pinpoint the source of the leak
while enabling it to register higher concentrations only.

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.
Replacing the Sensor
To ensure the accuracy of the meter, the sensor must be replaced periodically.
Thelifespanofasensordependsonseveralfactors:thetechnologyused,
environmentalconditionsandgasexposure.Themoreanelectrochemical
sensorisexposedtogas,theshorteritslife.Undernormalconditionsand
propercare,thesensorlifespanisapproximately1-2years.
Note: It is recommended to perform self-tests of the sensor prior to taking
readings to ensure that the sensor is still in working condition.
1. When ready to replace, remove the sensor protector cover from the
tip of the sensor probe. Be careful when before attempting to remove
thesensor,astheoldsensormaybeveryHOT.
2. If cool, pull out the old sensor and insert the new sensor into the plug
(seebelow).
3. Place the sensor protector over the new sensor.

Battery Replacement
When the low battery power is running low, the red LED low battery indicator
will illuminate conrming that the batteries will need to be replaced.
1. Loosen the battery cover screw and remove the battery cover
located on the bottom of the instrument as shown below.
2. Install4x"AA"batteries.
3. Replace battery cover by aligning it with the hangle and sliding it
back onto the unit.
4. Tighten the battery cover screw to secure back into place.
