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
Section
6.0 Troubleshooting
.
Detailed procedures of how to replace the sensor and other
components in the instrument are provided below.
5.1 Replacing the Sensor
Replacement sensors are classified at the factory according to
sensitivity, and are shipped with a matching resistor that
ensures the sensor will function properly when installed in
your instrument. It is important that the sensor and its
resistor be used together – DO NOT intermix resistors and
sensors.
Items required:
• Small and medium flat-blade screwdrivers
• Wire cutter
• Replacement sensor with matching resistor (P/N 19-0398)
