Safety Information
WARNING
Understand and follow operating instructions
carefully.
• If the equipment is used in a manner not specied
by the manufacturer, the protection provided by the
equipment may be impaired.
• Always use proper terminals, switch position, and
range for measurements.
• To reduce the risk of re or electric shock, do not
use this product around explosive gas or in damp
locations.
• Verify the Meter operation by measuring a known
voltage. If in doubt, have the Meter serviced.
• Do not apply more than the rated voltage, as
marked on Meter, between terminals or between
any terminal and earth ground.
• Avoid working alone so assistance can be rendered.
• Do not use the Tester if the Tester is not operating
properly or if it is wet.
• Individual protective device must be used if
hazardous live parts in the installation where the
measurement is to
be carried out could be accessible.
• Use caution with voltages above 30 Vac rms, 42
Vac peak, or 60 Vdc. These voltages pose a shock
hazard.
• DO NOT USE the test leads when the internal white
insulation layer is exposed.
• DO NOT USE the test leads above maximum
ratings of CAT. environment, voltage and current,
that are indicated on the probe and the probe tip
guard cap.
• DO NOT USE the test leads without the probe tip
guard cap in CAT III and CAT IV environments.
• Probe assemblies to be used for MAINS
measurements shall be RATED as appropriate for
MEASUREMENT CATEGORY III or IV according to
IEC 61010-031 and shall have a voltage RATING of
at least the voltage of the circuit to be measured.
• Disconnect circuit power and discharge all high-
voltage capacitors before testing resistance,
continuity.

Do not discard this product or throw away.
Do not attempt to repair this Meter. It contains no
user serviceable parts. Repair or servicing should
only be performed by qualied personnel.
Periodically wipe the case with a dry cloth and
detergent.
Do not use abrasives or solvents.
Preparation and Caution Before Measurement
Observe the rules of Warnings and Cautions.

Making Basic Measurements
CAUTION
• When connecting the test leads to the DUT (Device
Under Test) connect the common test leads before
connecting the live test leads ; when removing the
test leads, remove the live test leads before
removing the common test leads.
• Make sure that the buzzer sound is perceptible
before using it under high background noise
environment.

Voltage Measurement
LED indicates measured voltage is high than ELV
limit (50VAC and/or 120VDC).
Warning
• When batteries are not tted or are exhausted, the
tester still work when measuring> 45VAC and/or
>35VDC.
• Timing Rating (tr): 30 seconds, Recovery Time (rt):
240seconds,when measuring >300V, recovery time
is necessary.
• L/R LED may light up when measuring AC voltage.
• Due to the high internal resistance, capacitive and
inductive Voltage (ghost voltage) may be indicated.
