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.

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.

Note
Phase Rotation Test works only on 3 phase 4 wire
system. The result is unreliable on other systems.
It is necessary to check the result by test with reverse

• Single Pole Check is available for both test leads.
Remove one of test leads before performing check.
• Do not check if voltage appears by Single Pole

Warning
• For CAT III or CAT IV environments, use the test
leads with the probe tip guard cap xed rmly.
Without the probe tip guard cap, the test leads can
be used in CAT II environment ONLY.
• Make sure test leads are rmly connected to
instrument and other accessories.

Depending on the internal impedance of this meter
there will be a di󰀨erent capability of indicating the
presence or absence of operating voltage in case of
the presence of interference voltage.
When in contact with the parts to be tested, this
meter may discharge temporarily the interference
voltage to a level below the ELV, but it will be back to
the original value when this meter is removed.
When the indication “voltage present” does not
appear, it is highly recommended installing earthing
equipment before work.
When the indication “voltage present” appears on
a part that is expected to be disconnected of the
installation, it is highly recommended conrming by
another means (e.g. use of an adequate voltage
detector, visual check of the disconnecting point of
the electric circuit, etc.) that there is no operating
voltage on the part to be tested and to conclude that
the voltage indicated by this meter is an interference
voltage.
