procedure will reliably and repeatedly
pinpoint the leak with each pass over the
leak site.
If a large leak is present, the auto zero
circuit may reduce sensitivity to an
unacceptable level to find small and
medium sized leaks. If this condition
exists, use the manual mode to pinpoint a
large leak. The manual mode is also an
effective means to determine if a large
leak of any refrigerant exists prior to
searching for leaks (see Section 2.4).
In Manual Mode the auto-zero circuit is
disabled. The unit will not zero the leak if
the probe is held over the leak site. This
mode may require frequent readjustment
of the Manual Balance control to
maintain the required 1 tick per second
that indicates proper adjustment and
calibration for all three sensitivity switch
positions. Manual mode provides greater
sensitivity than auto mode.
