B. Detection Methods
1. Visually inspect the refrigerating system to check if any oil and dust on the pipeline,
any leak on the valve, copper welding spot or pipeline.
2. Move the probe to carefully check every possible area, and the speed of moving
probe is ≤ 1cm/s, and the probe distance should be kept in 1-3mm. See followings:
3. ① Alarming of device identifies the approaching leak location, repeatedly detect
the surroundings to check if any repeat alarm occurred.
② When the leak location is ensured, move the probe from different directions
of non-alarm area to the alarm area to locate the leak source.
③ Move the device away from the leak area, then reset the device and gradually
decrease the sensitivity to repeatedly locate the concrete leak source.
④ Mark it down then go on the detection for other parts of the whole refrigerating
system when the leak location is concreted.
