4.3 Using the Earphone
The earphone is an optional accessory that provides private
monitoring of the Leakator 10, and is recommended for use in
high-noise environments. The earphone plugs into the side of
the instrument, just above the thumb-wheel control.
4.4 Turning OFF the Instrument
Turn OFF the instrument by rotating the thumb-wheel con-
trol counterclockwise until a click is heard. There is no need
to purge the instrument with fresh air before turning it off.
5.0 MAINTENANCE
WARNING!
Do not replace the batteries, sensor, or sensor
matching resistor in a hazardous area.
Since the Leakator 10 does not require calibration at regular
intervals, very little needs to be done to maintain the instru-
ment in working order.
If the instrument has not been used for more than 3 months,
you may wish to turn it on and let it run in fresh air for several
minutes to keep the sensor at peak sensitivity.
If a problem should occur with your instrument, refer to Sec-
tion 6.0 Troubleshooting .
Detailed procedures of how to replace the sensor and other
components in the instrument are provided below.
