Adjusting Sensitivity Levels
The Leak Detector will default to the NORM sensitivity level
automatically once the unit comes out of the warm up cycle and
the green LED will turn on.
To change sensitivity levels, press the SENS once for HI
sensitivity (red LED will turn on) and again for LO sensitivity
(yellow LED will turn on).
Leak Test Vial
The leak detector comes with a Leak Test Vial that allows the
user to make sure the detector is performing properly. To test:
1. Remove the Plastic Seal Cap on the top of the Leak Test
Vial by pulling it off (see fig. below). Also, remove and
discard the circular Leak Test Cap Seal.
2. Turn on the leak 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
4-6 indicating that the sensor and electronics are working
properly.
NOTE: Remember to replace the Plastic Seal Cap after the leak
test is completed. Replace the Leak Test Vial when the green
media color is no longer visible and the leak media has evaporated.
Remove the threaded cap on the Vile to confirm the status of the
leak test media. After the leak test media has evaporated, it is
normal for there to be a green film on the wall of the Leak Test Vial.

fully inserted into the six-pin socket, or if it is defective, the
instrument will not come out of the “Warm Up” mode for proper
operation when the power button is turned on. Additionally, if the
instrument becomes unstable during its operation, it is an
indication that the sensor may be defective.
