*To avoid damages to the instrument, do not exceed
the 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, 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 the 9V NEDA battery, properly installed in the
Meter's battery case, to power the Meter.
*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 Category III,
or 1000V in Category II installations.
*Do not operate the Meter with the case
(or part of the case) removed.
