OPERATING INSTRUCTIONS
01.
Turn on: Press the ON/OFF button once to turn on and again to turn off.
02. Warm up: The detector automatically starts heating the sensor. During the heating cycle, the
digital leak size indicator will flash ‘0’ and the detector will sound a slow “beep”. Warm up is
usually less than 10 seconds.
03.
The detector is ready to begin searching for leaks when the flashing ‘0’ stops and the green
sensitivity LED turns on. The audio “beep” increases in frequency.
LEAK SIZE INDICATOR
The digital leak size indicator remains off normally but once a leak is detected, a number from
1-9 will be displayed for all combustible gases regardless of the sensitivity setting. The number
will continue to increase or decrease depending on the amount of combustible gas sensed. The
maximum value will be displayed once the leak source has been located.
LOW BATTERY INDICATOR
Replace the 4 AA Alkaline batteries when the red LED on the control panel is lit.
AUDIO MUTE FUNCTION
To silence or mute the audio beep and alarm signal, press the MUTE button. To restore the audio
sound, press the MUTE button again. (Note: a few seconds is required to restore sound if the
mute button is pressed in rapid succession.)
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:
01. Remove the colored label dot in the center of the screw cap to expose the vent hole in the
top of the screw cap.
02. Turn on the detector and allow the unit to complete the warm up cycle.
03. 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:
Replace the Test Vial back in the nylon bag when not in use to extend the shelf
life. Replace Test Vial when the green colour is less than ¼ full or at the time of the
expiration date.
