This meter has been designed according to IEC-61010
concerning electronic measuring instruments with a mea-
surement category (CAT II 600 V) and pollution degree 2.
To avoid possible electric shock or personal injury, follow
these guidelines:
Warning
Do not use the meter if it is damaged. Before you use
the meter, inspect the case. Pay particular attention
to the insulation surrounding the connectors.
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.
Do not operate the meter around explosive gas, vapor,
or dust.
Do not apply more than the rated voltage, as marked
on the meter, between terminals or between any
terminal and earth ground.
Before use, verify the meter's operation by measuring
a known voltage.
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 servicing the meter, use only specified
replacement parts.
Use caution when working above 30Vac rms, 42V peak,
or 60Vdc. Such voltages pose a shock hazard.
When using the probes, keep your fingers behind the
finger guards on the probes.
When making connections, connect the common test
lead before you connect the live test lead. When you
disconnect test leads, disconnect the live test lead first.
Remove the test leads from the meter before you open
the battery cover or the case.
Do not operate the meter with the battery cover or
portions of the case removed or loosened.
To avoid false readings, which could lead to possible
electric shock or personal injury, replace the battery as
soon as the low battery indicator ( " " ) appears.
When in Relative Mode, the symbol " " is displayed.
Caution must be used because hazardous voltage
may be present.
When in MIN mode, the symbol "MIN"is displayed.
Caution must be used because hazardous voltage
may be present.

Do not use the meter in a manner not specified by this
manual or the safety features of the meter may be
impaired.
Remaining endangerment:
When an input terminal is connected to dangerous live
potential it is to be noted that this potential at all other
terminals can occur!
CATII - Measurement Category II is for measurements
performed on circuits directly connected to low
voltage
installation.(Examples are measurements on
household
appliances, portable tools and similar equipments .)
Do not use the meter for measurements within
Measurement Categories III and IV.

Disconnect circuit power and discharge all capacitors
before testing resistance, diode, capacitor, temperature
and continuity.
Use the proper terminals, function, and range for your
measurements.
Before measuring current, check the meter's fuses and
turn off the power to the circuit before connecting the
meter to the circuit.
Before rotating the range switch to change functions,
disconnect test leads from the circuit under test.
Remove test leads from the meter before opening
the meter case or the battery cover.
Because of anti-interference designs, the meter may
stop working in strong interference environment. Turning
on the meter again can solve this problem.
