Combustible Gas Leak Detector/English
7-1.Hold Measurement
• Check for an appropriate work area as indicated in the General Safety Section.
• Determine the application and confirm that you have the correct equipment.
See the Specifications section for information on sensitivity, gases detected and other
information.
• Make sure that all equipment has been properly inspected.
• In an area where combustible gases are known to not be present, turn on the gas detector
by pressing and releasing the ON/OFF button. For one second the gas detector will
vibrate, beep, and the first level red light will come on to indicate that the unit is ON. The
gas detector then starts an approximately 50 second sensor heat up and calibration,
during which the first level red light is blinking.
Once the calibration is complete, for one second, all level lights will flash, and if the
audible and vibration alerts are ON, the unit will beep and vibrate. Then either the
high(yellow)or low(white)light will be ON. If the high(yellow)and low(white) sensitivity
lights are ON at the same time, this indicates that the batteries need to be charged. If all
display lights are ON, this indicates that the sensor has failed and that the unit needs to
be serviced.
If the gas detector is left ON for more than ten minutes with no activity and Auto Power
Off is enable, it will automatically shut OFF to conserve the batteries.
• The Audible Alert and Vibration Alert retain the previous state the detector was last in and
can be turned ON or OFF if desired. Press and release the Audible Alert button to turn it
ON and OFF. The gas detector will beep once when the Audible Alert is turned ON and
OFF. Press and release the Vibration Alert button to turn it ON and OFF. The gas detector
will vibrate twice when turning the Vibration Alert ON and vibrate once when turning the
Vibration Alert OFF.
• Enter the area to be monitored. Pay close attention to the gas level indicators (see Table
1). As gas levels increase, more red level lights will come on and the frequency of the
Audible Alert beeping and the Vibration Alert vibration will increase. See Table 1for
information on methane concentration levels and gas detector feedback.
• When the gas detector is turned ON it is in whatever sensitivity state it was last in. In the
low sensitivity setting, the lowest concentration of methane detected is 100ppm. Switch
the sensitivity to the high setting by pressing the high sensitivity button(H). This will be
indicated by the yellow light in the bottom right of the display. In the high sensitivity
setting, the gas detector is ten times more sensitive, with the lowest concentration of
methane detected at 40 ppm. Sensitivity can be changed at any time by pressing the High
Sensitivity(H) or Low Sensitivity (L)buttons.

If locating a leak, use the gas detector to find areas of lower gas concentration and follow
back to the source. In a piping system, trace the system, stopping at the joints to monitor
the gas levels.
• When gas detection is complete, turn the gas detecto OFF by pressing the ON/OFF button.
Table 1-Gas Detector Feedback For Methane Concentration Levels
Low Sensitivity High Sensitivity
White Light ON Yellow Light ON
= 0ppm = 0ppm
1 ...100ppm 1 ...1000ppm
100 ... 400ppm 1000 ... 4000ppm
400 ... 700ppm 4000 ... 7000ppm
700 ... 1000ppm 7000... 10000ppm
≥10000 ppm
≥1000ppm
Gas Concentration levels may differ depending on the specific gas detected.
7-2.Hold Measurement
Press and release the Hold button to enable or disable. When Hold is enable,
measurement is stopped and white light and yellow light stop blinking and ON. When
Hold is disable, measurement is running and white light and yellow light is blinking.
7-3.Auto Zero
Press and release the Auto Zero button to enable or disable. When Auto Zero is enable,
blue light under the Auto Zero button is ON. Enable Auto Zero can quickly adjust the zero
point of sensor, improve the sensitivity and reduce the interference of unknown gases.
7-4.Auto Power Off
Press and release the Auto Power Off button to enable or disable. When Auto Zero is
enable, blue light under the Auto Zero button is ON. If the gas detector is left ON for more
than ten minutes with no activity and Auto Power Off is enable, it will automatically shut
OFF to conserve the batteries.
