• Replace the battery as soon as the battery indicator
appears. With a low battery, the Meter might produce
false readings that can lead to electric shock and
personal injury.
• Do not measure voltages above 600V in CAT III,
or 1000V in CAT II installations.
• When in REL mode the REL symbol is displayed.
Caution must be used because hazardous voltage may
be present.
• Do not operate the Meter with the case (or part of the
case) removed.
maximum limits of the input values shown in the
technical specification tables.
• When the multimeter is linked to measurement circuits,
do not touch unused terminals.
• Caution when working with voltages above 60Vdc or
30Vac rms. Such voltages pose a shock hazard.
• When using the probes, keep your fingers behind the
finger guards.
• When making connections, connect the common test
lead before connecting the live test lead; when
disconnecting, disconnect the live test lead before
disconnecting the common test lead.
• Before changing functions, disconnect the test leads
from the circuit under test.
• For all dc functions, including manual or auto-ranging,
to avoid the risk of shock due to possible improper
reading, verify the presence of any ac voltages by first
using the ac function. Then select a dc voltage range
equal to or greater than the ac range.
• Disconnect circuits power and discharge all
high-voltage capacitors before testing resistance,
continuity, diodes, or capacitance.
• Never perform resistance or continuity measurements
on live circuits.
• Before measuring current, check the meter's fuse and
turn off power to the circuit before connecting the meter
to the circuit.
• In TV repair work, or when carrying out measurements
on power switching circuits, remember that high
amplitude voltage pulses at the test points can damage
the multimeter. Use of a TV filter will attenuate any
such pulses.
• Use only three AAA batteries, properly installed in the
Meter's battery case, to power the Meter.
