REFRIGERANT LEAK DETECTOR SEGO DTCTR
If the circuit detects a failed or missing sensor, it display
4.5 Audible / Visual alarms – Mute feature
The unit features two alarm indications – an internal speaker audible alarm and LED screen data visual alarm.
When detect the leakage, LED screen will display the leakage level. The leakage level is from 1-7. User could
select to activate both the audible and visual alarms, or use only the visual alarm. Upon power-on, the product
will automatically deactivate audible alarm. If you want to enable the audible alarm, press Alarm key, then the
internal speaker is enabled, and the leakage could be indicated by both LED screen and speaker.
Press Alarm Key again, the speaker alarm will be muted.
5. Operation
5.1 Press and release ON/OFF Key to switch on the detector.
5.2 The detector will start the warm-up. The middle LED will flash, warm-up indicator is on, and battery indicator
is on, and warm-up time is about 30 seconds.
5.3 After warm-up, the air pump indicator is on, it displays "0" and blinks, representing the device is ready for
use. Press Alarm key to enable audible indication, and the device will emit a stable beeping.
5.4 Set the sensitivity level according to user's demand, as described in the Sensitivity Adjustment Section.
5.5 Begin searching for leakage. Move the probe tip toward the suspected leak. The flexible probe may be
shaped to provide access to hard-to-reach areas.
NOTE: If the device has previously been used, make sure that the probe tip is not obstructed with dirt, grease,
etc.
5.6 If a refrigerant is detected, the device will begin to alarm – the audible tone will quicken and it displays
number of leakage level. The larger of the detected concentration, the greater it alarms.
5.7 If an alarm occurs before the leak source is pinpointed, the Reset Key may be used to pinpoint the leak, as
described in the Reset Features section. The unit may be reset as many times as necessary to pinpoint the leak
source. It is suggested to wait for about ten seconds to detect the leakage after pressing rest key.
6. Detection method:
As for the detection method, please see Figure 3
6.1. Visually exam the refrigeration system. The oily and dirty spots, node valves, coils, connectors, or pipelines
are the areas most likely to leak gases.
6.2. Start leak detecting at the joint at a speed of 1cm/s and the distance between sensor tip and the joint should
be 1-3mm.
