Detecting method
Detecting method
Halogen leak detector operation method:
When the detector is turned on or off by long pressing POWER key, all LED indicator lights are on for three seconds and the
detector will automatically reset. After auto-reset, only the first LED indicator light on the left will be on. (Green, batteries
fine, orange, batteries getting weak, replace as soon as possible; red indicates the batteries need to be replaced before
normal detecting). At this time, the beeping sounds regularly and the detector sets the atmosphere halogen level to “zero”,
ready for detection.
Operation instruction
1.
Check the battery level by observing the constant power indicator light.
2.
Once turn on the detector, the default sensitivity level is level 4. You will hear rapid, but steady beep sound. The
sensitivity can be adjusted by pressing SENSITIVITY ” “ or SENSITIVITY “ “ according to your requirement.
3.
Begin searching for leaks. When refrigerant is detected, a siren will be sounded, with a rate quite different from
previous beep sound. And the indicator lights will progressively turn on.
4.
Sensitivity can be adjusted at any time during operation by pressing ” “ and “ “ key. This adjustment will not
interrupt detection.
5.
If alarm occurs before the sensing tip touches with the leakage source, press “Reset” key to reset the current to 0
until there is no alarm, then you could detect again.
6.
Press “ Mute” key to close the alarm sound; press it again to activate alarm sound, loop operation.
7.
Press the “BATTERY TEST” key to check the battery level.
Halogen leak detector detecting method:
See Figure 4
1.
Visually exam the refrigeration system. The oily and dirty spots, node valves, coils, connectors, or pipelines are the
areas most likely to leak gases.
2.
Start leak detecting at the joint at a speed of 1cm per second and the distance between sensor tip and the joint
should be 1-3cm.
3.
When an alarm is triggered, it may indicate a leak is close by. Detect around that area again and see if the alarm is
repeatable. If a leak is confirmed, pinpoint the leak source by moving slowly from no-leaking (no-alarm) area to the
leaking area from different directions. Besides, you could also pinpoint the leak by moving the detector away from
the leaking area and reset the unit, adjusting the sensitivity lower and repeating the above process.. Once confirmed,
mark around the leak and continue detecting the whole line of the system.
