WARNING
To reduce the risk of fire or electric shock, do not expose this product to rain or
moisture. To avoid electrical shock hazard, observe the proper safety precautions when
working with voltages above 60 VDC or 30 VAC rms. These voltage levels pose a
potential shock hazard to the user. Do not touch test lead tips or the circuit being tested
while power is applied to the circuit being measured. Keep your fingers behind the
finger guards of the test leads during measurement. Inspect test leads, connectors, and
probes for damaged insulation or exposed metal before using the instrument. If any
defects are found, replace them immediately. Do not measure any current that exceeds
the current rating of the protection fuse. Do not attempt a current measurement to any
circuit where the open circuit voltage is above the protection fuse voltage rating.
Suspected open circuit voltage should be checked with voltage functions. Never attempt
a voltage measurement with the test lead inserted into the
A/mA or A input jack. Only
replace the blown fuse with the proper rating as specified in this manual.
CAUTION
Disconnect the test leads from the test points before changing functions. Always set the
instrument to the highest range and work downward for an unknown value when using
manual ranging mode.
