6.2 Operating Details
a)
Power-on Self-detection: Long press POWER button
by level and then off (meanwhile with Di sound), followed by Yellow/Orange/Red light on
then off. Reset as per the current gas condition, with regular Di sound in device, backlight
of POWER button in green, finishing the
normal detection.
b) Detection: Hold the device to move probe to find the leak location in the pipeline and
interface of refrigerating system. When the refrigerant is detected, there will be with Di
sound increasing in frequency, and alarm lights in Yellow/Orange/Red are on level by level
as per the leak concentration.
c) Sensitivity Adjustment: The default sensitivity of device is level 3, and short press

avoid any potential leak missed. Mark it down and go on the detection when any leak
area is detected.
c) The speed of moving probe should be ≤
distance should be kept in 1-3mm. See followings:
d) ①Alarming 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
