Low battery indication
Replace the batteries when the red low battery
LED comes on (see page 3). Follow instruc-
tions under section titled "BATTERY IN-
STALLATION" on page 3.
Audio alarm mute (
AccuProbe UV
)
To silence the audio alarm,
press the MUTE button. Press
the MUTE button again to
restore the audio alarm.
Sensor failure mode
If the sensor is not working correctly, the
AccuProbe Leak Detector will not come out of
the warm-up mode. (Some competitive units
without this function will not alert you that the
sensor is malfunctioning or has failed.)
If the AccuProbe detector does not come out
of warm-up, first be sure the sensor is plugged
in all the way. If that does not correct the situa-
tion, replace the sensor.
Maintenance
Batteries:
Replace the batteries when the
red low battery LED turns on. See “BATTERY
INSTALLATION” on page 3.
Sensor filter replacement:
Unscrew the
sensor tip as shown to replace the filter. For
optimum performance, replace filter whenever
it becomes visibly dirty with grease or oil or
every 2-3 months (depending on use).
Note: Never clean dirty filters with a solvent
or soap and water. Always replace with a
new filter supplied with the leak detector or
they can be re-ordered from your supplier
or distributor.
Sensor replacement:
Remove sensor by
pulling out of socket. Install the new sensor by
aligning the notch in the sensor cover with the
raised keyway on the sensor socket holder (see
Figure 2).
Note: Do not force sensor into socket.
Misalignment can damage the sensor pins.
