1. GENERAL INFORMATION
Thank you for purchasing Combustible Leak Detector.
Read though the instruction manual before operation
for correct and safe usage. Please store and retain
this instruction manual for future reference.
2. FEATURES
Combustible Leakage Detector is extremely useful as
a general purpose tool in any environment where
gasoline, propane, natural gas or fuel oil is used. This
unit uses a newly developed semi-conductor sensor
which is extremely sensitive to variety of general
used combustible.
Microprocessor Control with advanced digital
signal processing.
Multi color visual display.
High-Low leak sensitivity selector.
Low battery indication.
Semiconductor gas sensor.
Detection of combustible gas.
Carrying case included.
15.5” (40 CM) flexible stainless probe.
Reference Leak source included.
Ambient concentration reset.
Application:
Detect leaks in automobile exhaust and fuel
system.
Detect leaks in liquid or gas fired heating systems.
Safety checks at propane filling stations.

4. OPERATION GUIDE
(1) The combustible leak detector unit is not equipped
with anti-explosive designs and measures. Do not use
this unit in the environment with the burnable gases.
(2) There are some environmental conditions that
might cause error reading:
Pollutant places.
Large temperature variation.
Places with high wind velocity.
Organic solvent, adhesive vapor, fuel gas and
vesicant will cause abnormal response from the
sensor. Try to avoid the environment involved with
this substance.
Places fill with too much to combustible Gas.
Note: Although the unit will respond to high levels of
carbon monoxide, it should not be used as a detector
for this gas in normal room or working atmospheres.
It is used to pinpoint a leak as described in the
operating instruction.

6. GETTING STARTED
6-1 Installing Batteries
Loose the screw and remove the battery
compartment door located on the bottom of the
instrument as shown below (Fig.1).
Install 4 “AA” size alkaline batteries.
Reinstall the battery cover by aligning it with the
handle.
When the battery power is running low, the Red LED
Low Battery indicator illuminates. The batteries should
be replaced as quickly as possible.

6-2 Automatic Ambient Reset Feature
This combustible leak detector features an Automatic
Ambient Reset function that sets the unit to ignore
ambient concentrations of combustible.
Automatic Ambient Setup - Upon initial power on,
the unit automatically sets itself to ignore the level
of combustible present at the tip. Only a level, or
concentration, greater than this will cause an alarm.
CAUTION!
Be aware that this feature will cause the unit to
ignore any combustible present at turn on. In other
words, with the unit off if you place the tip up to a
known leak and switch the unit on, no leak will be
indicated!
Ambient Reset Feature - Resetting the unit during
operation performs a similar function; it programs
the circuit to ignore the level of combustible
present at the tip. This allows the user to 'home-in'
on the source of the leak (higher concentration).
Similarly, the unit can be moved to fresh air and
reset for maximum sensitivity. Resetting the unit
with no combustible present (fresh air) causes any
level above zero to be detected.

6-3 Feature Sensitivity Adjustment
The Instrument provides two levels of sensitivity.
When the unit is switched on, it is set to the high
sensitivity level by default.
To change the sensitivity, press the key.
When the key is pressed, the visual display will
momentarily show the two left LED's (green)
indicating Low Sensitivity level is selected.
To switch back to High Sensitivity, press the
key. The two right LED's (red) will light momentarily
indicating high Sensitivity level is selected.
7. OPERATING PROCEDURE
WARNING!
1. Do not use the instrument in an area of
extremely high level of combustible gas.
2. The gas/vapor of organic solvent might
interfere with the function of the unit. During
detection, please eliminate the influence of the
organic solvent.
3. In order to ensure correct operation and
indication, the unit should be switched on and
warm-up in non-contaminated atmosphere.
