Auto-Balance Function:
To decide the method to screen the background
signal off.
(1)
On (default setting):
The tester will use the time averaging of the total
signal as its background level and seeking for
higher concentration space. Under this setting,
the user should move the sensor slowly around
the testing area to seek the potentially leaking
location.
Note:
The unit can be moved to fresh air and reset
for background signal level sensitivity. Resetting
the unit with no refrigerant present (fresh air)
causes any level above zero to be detected.
(2)
Off:
The tester will use a selected signal level and
show the concentration increasing as the sensor
move around. The background signal level can
be set anytime by pressing the “Auto” button to
reselect the new reference level. Under this
mode, it will be helpful to point out the exact
location of the leaking.
