SAFETY INFORMATION
This meter has been designed according to IEC 61010
concerning electronic measuring instruments with a
measurement category ( CAT III 300V ) and pollution
degree 2.
To avoid possible electric shock or personal injury,
Warning
This meter is a compact 3 ½ digit, digital multimeter,
designed to measure DC and AC voltage, DC and AC
current, resistance, diode, continuity and battery.
Some models also have temperature measurement
function, frequency measurement function, non-contact AC
voltage detection function, or live ac wire detection function
This multimeter features backlight, data hold, full-range
overload protection, illumination function, etc
It is an easy to operate, useful testing tool.

follow
these guidelines:
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 where explosive gas, vapor,
or dust is present.
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 with voltage above 30V AC
rms, 42V peak, or 60V DC. Such voltages pose a shock
hazard.
4
When using the probes, keep your fingers behind the
finger guards on the probes.
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.
Do not use the meter in a manner not specified by this
manual or the safety features provided by the meter
may be impaired.
Adhere to local and national safety codes. Individual
protective equipment must be used to prevent shock
and arc blast injury where hazardous live conductors
are exposed.
To void electric shock and personal injury, do not touch
any naked conductor with hand or skin; and do not
ground yourself while using this meter.
Do not use the meter if the meter, a test lead or your
hand is wet.
Caution
To avoid possible damage to the meter or to the
equipment under test, follow these guidelines:
Disconnect circuit power and discharge all capacitors
thoroughly before testing resistance, diode, continuity
or temperature.
Use the proper terminals, function and range for your
measurements.
5
Remaining endangerment:
When an input terminal is connected to dangerous live
potential it is to be noted that this potential can occur
at all other terminals!
CATIII - Measurement Category III is for
measurements performed in the building installation.
Examples are measurements on distribution boards,
circuit breakers, wiring, including cables, bus-bars,
junction boxes, switches, socket-outlets in the fixed
installation, and equipment for industrial use and some
other equipment, for example, stationary motors with
permanent connection to the fixed installation.
Do not use the meter for measurements within
Measurement Categories IV.

Caution, risk of electric shock.
Earth (ground) Terminal
Fuse
Conforms to European Union directives
The equipment is protected throughout by double
insulation or reinforced insulation.
Before measuring current, check the meter's fuses and
turn off power to the circuit before connecting the
meter to the circuit.
Before turning the rotary switch to change functions,
disconnect the test leads from the circuit under test.
