Cleaning Your Multimeter
Dirt or moisture in the terminals can distort readings.
Follow the steps below to clean your multimeter.
1 Turn the multimeter off and remove the test leads.
2 Turn the multimeter over and shake out any dirt that may
have accumulated in the terminals.
Wipe the case with a damp cloth and mild detergent — do
not use abrasives or solvents. Wipe the contacts in each
terminal with a clean swab dipped in alcohol.
WARNING
To avoid electrical shock or damage to the multimeter, ensure that
the insides of the casing stay dry at all times.
