General Maintenance
Besides the above hazard, dirt or moisture in the terminals
can distort readings. The steps for cleaning are as follows:
1 Turn the meter off and remove the test leads.
2 Turn the meter over and shake out any dirt that may
have accumulated in the terminals.
3 Wipe the case with a damp cloth and a mild detergent —
do not use abrasives or solvents. Wipe the contacts in
each terminal with a clean swab dipped in alcohol.
Ensure that the terminal connections are correct for that particular
measurement before proceeding. To avoid damaging the device, do not
exceed the input limit.
