possible leak source.
 Slowly move the probe past each possible leakage
point.
 When the instrument detects a leak source, the
audible tone will alarm. Additionally, the visual
indicators will light from left to right; Green LED
then Orange LED then Red LED (highest
concentration) as increasing of level indicate that
the location is close to the source.
 When the Instrument signals a leakage, pull the
probe away from the leak for a moment, and then
bring it back to pinpoint the location. If the
combustible leak is large, setting the sensitivity
switch to LOW will make it easier to find the exact
site of the leak.
 Return the sensitivity switch to HIGH before
searching for additional leaks.
 When you've finished leak-testing, turn OFF the
instrument and store it in a clean place, protect the
leak detector from possible damage.

The sensor has a limited operative period. Under
normal operation, the sensor should work more than
one year. Expose the sensor under high density of
coolant (>30000ppm) will shorten its life cycle rapidly. It
is important to ensure that sensor surface is free from
