Color-coded LED level indicators 3. Sensitivity select buttons (Low, High) 4. Battery status LED 5. Power ON/OFF button 6. Removable sensor access collar 7.
Operation Note: Power OFF the system under test before attempting to find leaks. Powering the Meter 3. Short press the ON/OFF button (5) to power the meter.

While powering on, the leak-level LEDs (2) will light in sequence (left to right) and the start-up tone will sound once. 5.
near all potential sources of leaks and gage the meter’s response by observing the color-coded leak-level LEDs and listening for the audible tones. Always make measurements along a continuous route for best results. 4. The two green LEDs represent the absence of a leak or a very small leak, the two yellow LEDs represent a moderate leak, and the three red LEDs represent the detection of a large leak. 5.
Measurement Considerations If you do not detect a leak, try the low sensitivity mode (press Low sensitivity button) and check again. If there is wind in the area of test, shielding the suspected leak area from the wind will yield better results. Do not allow moisture or solvent near the sensor, this may introduce false alarms. When you suspect a large leak, using compressed air in the area of the leak may help determine the exact location of the leak.
4. Secure the battery compartment and replace the protective jacket before operating the meter. Never dispose of used batteries or rechargeable batteries in household waste.
