WARNING
Safety Information
This multimeter complies with the standards
IEC61010: in pollution degree 2, overvoltage
category (CAT. II 600V), and double insulation.
Use the multimeter only as instructed in
this operating manual, or the device may be
damaged, and you may be seriously injured.
In this manual:
WARNING : Identies conditions and
actions that are hazardous to the user or may
damage the multimeter and test leads while
operating.
NOTE: Identies the information that the user
should pay attention to.
• Please read and follow all of the
instructions and warnings in this
manual before using the product.
Failure to comply with the instructions
may result in serious injury, re,
and/or electrical shock. The person
responsible for this equipment must
ensure that all users understand and
follow the instructions.
• TO AVOID THE RISK OF ELECTRIC
SHOCK OR DAMAGE TO THE
MULTIMETER OR OTHER EQUIPMENT,
DO NOT CONNECT LEADS TO POWER
SOURCES THAT MAY EXCEED 600V.
• Expired or damaged batteries can
cause burns upon contact with skin.
ALWAYS wear proper hand protection
when handling expired or damaged
batteries.
• DO NOT alter the internal circuitry of
the multimeter. Doing so may damage
the device and will void your warranty.

• DO NOT use the multimeter if it is damaged
or if any part of the case is removed. Always
inspect all parts of the multimeter, the case,
and the test leads before each use.
• DO NOT use or store the multimeter in wet
or humid environments, in high-temperature
areas, around explosive or ammable
substances, or in areas with strong magnetic
elds.
• DO NOT allow children to use or play with
this device.
• DO NOT measure voltages when the
multimeter is set to measure resistance (Ω)
or current (A).
• Take special care to avoid electric shock
when the multimeter is working at an
effective voltage over 60V DC or 30V rms
AC.
• DO NOT change the settings on the rotary
switch while the test leads are connected to
a power source.
• DO NOT operate the multimeter with the
battery cover removed or without the case.
• DO NOT remove the case or open the
battery cover while the multimeter is
connected to a power source.

Before First Use
• When setting up the multimeter, connect
the black test lead before connecting the
red test lead. To disconnect, take out the
red test lead before removing the black
test lead.
• Inspect the test leads for damaged insulation
or exposed metal parts. Check the leads for
continuity (see page 12). Replace damaged
test leads if necessary.
• Keep your ngers behind the nger guards
at all times when handling the test probes.
• ALWAYS remove the test leads from the
item being measured before changing the
settings.
• Check the fuses in the multimeter before
measuring current. Always make sure power
to the circuit has been shut off before
connecting the multimeter to the circuit.
Once you have properly connected the
multimeter, power on the circuit.
• Remember to replace the batteries as soon
as the low battery indicator “ “ appears
(see Replacing the Batteries, page 16). The
multimeter may produce incorrect readings
if it is operated with a low battery, which can
result in electric shock or injury.
• Whenever you nish measuring an object
with the multimeter, disconnect the test
leads from the object.

ii. AC or DC Measurement
1. Insert the black test lead into the COM
terminal, and the red test lead into the
terminal.
2. Turn the rotary dial to .
Note: The default function is DC. Press
SEL/REL to switch between AC and DC
measurement.
3. Connect the test leads to the object
being measured. Hold them in place until
the readings on the display stabilize.
4. When the measurement is complete,
disconnect the test leads from the
object, then remove the test leads from
the multimeter.
Note: In each range, the multimeter has
an input impedance of 10 MΩ . This loading
effect can cause measurement errors
in high impedance circuits. If the circuit
impedance is less than or equal to 10 MΩ ,
the error is negligible (0.1% or less).
Voltage Measurement
Operation
WARNING
DO NOT measure voltages higher than
600V. Doing so may result in electric
shock, damage to the multimeter, or
injury to the user. Always take extra
care to avoid electric shock when
measuring high voltages.
i. AC or DC Voltage
1. Insert the black test lead into the COM
