5 | ACT925 Operators Manual

Adjusting Sensitivity Levels

In addition to the automatic calibration, the audio alarm trigger level can be
set by the user to 3 different sensitivity levels (LO, MED, HI).
detector is continually alarming away from the suspected area of the leak,
the sensitivity level can be adjusted so the detector will only alarm when
the sensor is close to the source of the leak.
The Leak Detector will default to the MED sensitivity level automatically
once the unit comes out of the warm up cycle. To change sensitivity levels,
press the LO MED or Hi sensitivity button. The LED Indicator will change
colors Yellow for LO, Green for MED and Red for HI.

Leak Test Vial

The leak detector comes with a Leak Test Vial that allows the user to
make sure the detector is performing properly. Check the expiration date
before to test the leak detector.
NOTE: the expiration date of the test vial is 15 months (label on the vial). After
removing the seal over the small hole in the cap, it reduces to 12 months.
To test:
1. Remove the colored label dot in the center of the screw cap to
expose the vent hole in the top of the screw cap. (see fig. below)
2. Turn on the detector and allow the unit to complete the warm up
cycle.
3. Place the sensor close to the small hole in the top of the Leak Test
Vial. The beep rate should increase and the Digital Leak Size
Indicator should display a number from 3-6 indicating that the
sensor and electronics are working properly.
NOTE: the leak detector responds to changes in refrigerant concentration. When
detection occurs, move the probe away from the source and back again to
confirm the leak source. The detector alarm will reset if the probe is held fixed at
the source (see Automatic Calibration Feature).
