OPERATION INSTRUCTIONS:
1. Turn the unit off and turn the sensitivity knob fully counter
clockwise.
2. Turn the unit on in a non-contaminated atmosphere with the slide
switch, the power indicator will light up. Power indicator shows the
battery power is sufficient, it ensures precise detection.
3. After the unit is turned on, it will auto warm-up within 110
seconds, a ticking sound will be heard.
4. Adjust the sensitivity control until the first leak indicator lights up,
and the ticking frequency increases.
5. Approaching known leak source, the leak size indicate lights will
increase with the rapid ticking. Above steps are necessary to
ensure the unit is working correctly. Now the unit is ready for use.
If the battery power is in sufficient state, but the sensor
approaches known leaks without any responses, do not use the
instrument, please return for repair.
6. In conjunction with the increased tick rate, the leak size indicator
will light from bottom to top as combustible gas concentration
grows.

enters the sensor, the tick rate speeds up.
8. If you are searching for a heavy leak source, please lower the
sensitivity in a clear air by turning the adjustable knob (until the
leak size indicator turns off).
