Safety Precautions
•
Do not use the meter if you are unfamiliar with electric circuits and testing procedures.
•
To avoid electric shock, disconnect both test leads from the circuit under testing before
you replace the batteries and fuse.
•
Do not operate the meter until the batteries are properly installed and the back cover
and battery compartment cover are in place and secured.
• Use extreme caution when working with voltages above 30V RMS and 42.4V peak or 60V
DC. Always disconnect power from the circuit you are measuring before you connect test
leads to high-voltage points.
•
Never connect to a voltage source when you select the diode check, continuity function,
resistance measurement, or any of the battery test or current measurement functions.
•
Always discharge any capacitors of the circuit under test before you attach test leads and
always turn off power and disconnect the test leads from the circuit before replacing the
meter’s batteries or the fuse.
•
Because many AC/DC sets have a potentially hot chassis, be sure the top of your
workbench and the floor underneath it are made of nonconductive materials.
•
If you connect one test lead to a hot wire first and touch the other test lead tip, you
could receive an electric shock.
