Remove the test leads from the Meter
before the battery door on the Meter
base is opened.
Examine the test leads for damaged
insulation or exposed metal. Measure the
test leads for continuity. Replace
damaged test leads before you use the
Meter.
Do not apply more than the rated
voltage, shown on the Meter, between
the terminals or between a terminal and
earth ground.
Do not operate the Meter with the battery
door removed or the case open.
Be careful around voltages >30 V ac rms,
42 V ac peak, or 60 V dc. These voltages
pose a shock hazard.
Use only the replacement fuse specified
by the manual.
Use the correct terminals, function, and
range for measurements.
Do not work alone.

incorrectly. Protection can be
compromised. If you are unsure, have
the Meter examined.
