� Warning and Percautions
Do not operate the meter in explosive gas (material),combustible
gas(material) steam or filled with dust.
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. S
uspected open circuit voltage should be checked with voltage functions.
Never attempt a voltage measurement with the test lead inserted into the
µA/mA or A input jack.
Only replace the blown fuse with the proper rating as specified in this
manual.
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.
To avoid electrical shock, disconnect the meter from any circuit, remove
the test leads from the input jacks and turn OFF the meter before opening
the case. Do not operate with open case.
