•
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 use the Meter around explosive gas, vapor or in
damp or wet environments.
•
Use only three 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.
•
Do not use the Low-Pass Filter to verify the presence of
hazardous voltages. Voltages greater than what is
indicated may be present. First, make a voltage
measurement without the filter to detect the possible
presence of hazardous voltage. Then add the filter.
To avoid possible damage to the Meter or to the equipment
under test, follow these guidelines:
•
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.
•
Before measuring current, check the Meter's fuses. (See
"Fuse Test".)
