you open the battery door.
Inspect the test leads for damaged
insulation or exposed metal. Check the
test leads for continuity. Replace
damaged test leads before you use the
meter.
Do not use the meter if it operates
abnormally. Protection may be impaired.
When in doubt, have the meter serviced.

Use only a single 9 V battery, properly
installed in the meter case, to power the
meter.
When servicing the meter, use only
specified replacement parts.
Caution
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 your measurements.
Before measuring current, check the
meter's fuses. (See "Testing the Fuses".)
