When the Instrument signals a leakage, pull the
probe away from the leak for a moment, then bring it
back to pinpoint the location. If the refrigerant 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 se-
arching 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.

Replacing new sensor
The sensor has a limited operative period. Under nor-
mal operation, the sensor should work more than one
year. Expose the sensor under high density of refrige-
rant (>30000ppm) will shorten its life cycle rapidly. It
is important to ensure that sensor surface is free from
water droplets, vapor, oil, grease, dust and any or all
other forms of contaminant. Furthermore, to ensure
good working condition of the unit, sensors must be
replacement periodically when its operative life is over.
WARNING! When replacing new sensor, the
worn-out sensor may be HOT!
Remove cone cap cover
from the tip of snake
tube.
Pull out old sensor and
insert the new sensor into
the plug.
Seal the cap cover over the plug.
