5. MAINTENANCE

5.1 General Maintenance

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.

- Work the swab around in each terminal. The oiling agent

insulates the terminals from moisture-related contamination.

meter, do not get water inside the case.

Remove the test leads and any input signals

before opening the case
