 Inspect the test leads for damaged insulation or exposed
metal. Check test lead continuity. Damaged leads must be
replaced. Do not use the meter if it appears damaged.
 Use care when working above 30V ac rms, 42V ac peak and
60V dc. Such voltages pose a shock hazard.
 When using the probes, keep fingers away from probe
contacts. Keep fingers behind the finger guards on the
probes.
 Measurements can be adversely affected by impedances of
additional operating circuits connected in parallel or by
transient currents.
 Verify operation prior to measuring hazardous voltages
(voltages above 30V ac rms, 42V ac peak and 60V dc).
 Do not use the meter with any of the parts removed.
 Do not use the meter near explosive gas, vapor, or dust.
 Do not use the meter in a wet environment.
