6. M A I N T E N A N C E
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.
6.1 General Maintenance and Cleaning
To avoid electrical shock or damage to the multimeter, do not get
water inside the case. Remove the test leads and any input signals
before opening the case.
Cleaning the multimeter:
• Wipe the case with a soft damp (not wet) cloth and mild detergent.
• DO NOT use abrasives or solvents.
• Dirt or moisture in the terminals can affect readings.
Cleaning the terminals:
• Turn the meter off and remove all test leads.
• Shake out any dirt that may have gathered in the terminals.
• Soak a clean swab or cotton bud with a cleaning and oiling agent (such as WD-40).
• Work the swab/bud around in each terminal until you are happy there
are clean. The oiling agent insulates the terminals from moisture-related
contamination.
