When measuring current, turn off circuit power before
connecting the Meter in the circuit. Remember to place the
Meter in series with the circuit.
When making electrical 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.
Do not use the Meter if it operates abnormally. Protection
may be impaired. When in doubt, have the Meter serviced.
Do not operate the Meter around explosive gas, vapor, or
dust.
Use only 1.5 V AA batteries, properly installed in the Meter
case, to power the Meter.
When servicing the Meter, use only specified replacement
parts.
When using probes, keep fingers behind the finger guards
on the probes.
Only use test leads that have the same voltage, category,
and amperage ratings as the meter and that have been
approved by a safety agency.
Use proper protective equipment, as required by local or
national authorities, when working in hazardous areas.
Comply with local and national safety requirements when
working in hazardous locations.
Disconnect circuit power and discharge all high-voltage
capacitors before testing resistance, continuity, diodes, or
capacitance.
Use the proper terminals, function, and range for all
measurements.
Do not remove batteries while the Meter is turned on or a
signal is applied to the Meter's input jacks.
Before measuring current, check the Meter's fuses. (See
"Testing the Fuses" in the Users Manual on the
accompanying CD.)
