5. MAINTENANCE
This section provides basic maintenance information, including fuse and battery replacement instructions.
Do not attempt to repair or service your Meter unless you are qualified to do so and have the relevant calibration,
performance test, and service information.
5.1 General Maintenance
To avoid electrical shock or damage to the meter, do not get water inside the case.
Remove the test leads and any input signals before opening the case
Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents.
Dirt or moisture in the terminals can affect readings.
To clean the terminals:
Turn the meter off and remove all test leads.
Shake out any dirt that may be in the terminals.
Soak a new swab with a cleaning and oiling agent (such as WD-40).
Work the swab around in each terminal. The oiling agent insulates the terminals from moisture-related
contamination.
