WARNING
Do not expose the meter to rain or moisture in order to reduce the risk of
fire or electric shock.
Observe the proper safety precautions when working with voltages above
30 V ac rms, 42 V ac peak, or 60 V dc. These voltage levels pose a potential
shockhazardtotheuser.
Inspect test leads, connectors and probes for damaged insulation or exposed
metal before using the meter.
Check the test leads for continuity before use. Do not use if the readings
are high or noisy.
Keep your fingers behind the finger guards of the test leads during
measurement.
Disconnect the test leads from the points before changing functions.
Disconnect circuit power and discharge all high voltage capacitors before
testing resistance.
Always use the proper terminals, switch position, and range for measurements
before connecting the meter to circuit under test.
When servicing the meter, use only specified replacement parts.
Remove test leads from the meter before you open the battery cover.

Avoid working alone.
CAUTION
Disconnect the test leads from the points before changing functions.
Disconnect circuit power and discharge all high voltage capacitors before
testing resistance, or continuity.
Always set the meter to the highest range and work downward for an
unknown value in the manual ranging mode.
