I. SAFETY :
The accompanied test probe assembly meets UL/IEC/EN61010-
031 Ed. 2.0 to the same meter ratings or better. IEC 61010-031
requires exposed conductive test probe tips to be ≤ 4mm for CAT
III & CAT IV ratings. Refer to the category markings on your probe
assemblies as well as on the add-on accessories (like detachable
Caps or Alligator Clips), if any, for applicable rating changes.
The meter meets UL / IEC / EN61010-1 Ed. 3.0, CAN / CSA C22.2
No. 61010-1Ed.3.0, UL/IEC/EN61010-2-032 Ed.3.0, UL/IEC/

serious injury or even death to the user.
CAUTION Identifies conditions and actions that could cause
damage or malfunction in the instrument.
01
WARNING :
This manual contains information and warnings that must be
followed for operating the meter safely and maintaining the meter in
a safe operating condition. If the meter is used in a manner not
specified by the manufacturer, the protection provided by the meter
may be impaired.
Observe proper safety precautions when working with voltages
above 30 Vrms, 42.4 Vpeak or 60VDC. These voltage levels pose a
potential shock hazard to the user. Do not expose this product to

WARNING : Before and after hazardous voltage measurements,
test the voltage function on a known source such as line voltage to
determine proper meter functioning.
ACV :
Inputs, are made through the test lead terminals COM/+. Defaults
at ACV Function.
Note : ACV function is equipped with low-pass filter, & is capable of
dealing with VFD (Variable Frequency Drive) signals. It also improves
ACV reading stability in noisy electrical environments.

Clamp-on Current Measurements :
Application & Removal of the Jaws
Press the jaw trigger & clamp the jaws around conductor(s) of only
one single pole of a circuit for load current measurements. Make
sure the jaws are completely closed, or else it will introduce measure-
ment errors. Enclosing conductors of more than one pole of a circuit
may result in differential current (like identifying leakage current)
measurements. Align the conductors to the Jaws center indicators
(Regular or AmpTipTM indicators where applicable) as much as
possible to get the best measuring accuracy. For removal, press the
jaw trigger and remove the jaws from the conductors.
Adjacent current-carrying devices such as transformers, motors and
conductor wires may affect measurement accuracy. Keep the jaws
away from them as much as possible to minimize influence.
WARNING :
This Clamp-on meter series is designed to directly apply around or
remove from uninsulated hazardous live conductors. But still,
individual protective equipment must be used if hazardous live parts
in the installation where measurement is to be carried out could be
accessible. Do not use the meter to measure currents above the
rated frequency (400Hz). Circulating currents may cause the
magnetic circuits of the Jaws reach a hazardous temperature.

 Resistance, BeepLit Continuity & BeepLit Diode :
Inputs are made through the test lead terminals COM/+.
Defaults at  Resistance. Press SELECT button momentarily to
select the subject functions in sequence.
This function is having improved convenience for checking wiring
connections and operation of switches. Resistance threshold is being
used. A continuous beep tone together with flashing display backlight
indicate a complete wire. Such audible and visible indications improve
continuity readabilities in noisy working environments.
TM
BeepLit Continuity :
Reading indication : Forward voltage drop (forward baised) for a good
silicon diode is between 0.400V to 0.900V. A higher reading indicates
a leaky diode (defective). A zero reading indicates a shorted diode
(defective). An over-range display indicates an open diode (defective)
Reverse the test leads connections (reverse biased) across the diode.
The digital display shows over-range if the diode is good. Any other
readings indicate the diode is resistive or shorted (defective).
TM
BeepLit Diode :
TM
Beep-Alert & BeepLit Indication :
When the display reading drops across 0.850V, the meter alerts a
short beep to signal a reasonable forward voltage drop of common
diodes. However, if the reading further drops below 0.100V, the meter
gives a continuous beep tone together with flashing display back-
light to indicate a shorted diode or a complete wire. it is similar to
TM TM
that of BeepLit Continuity function but BeepLit Diode, instead,
is based on voltage threshold to indicate a complete wire.
TM
BeepLit Diode function is located in an independent rotary
switch position.
15
CAUTION :
TM TM
Using Resistance, BeepLit Continuity or BeepLit Diode function in
a live circuit will produce false results and may damage the meter. In
many cases, the suspected components must be disconnected from
the circuit to obtain an accurate measurement reading.

field that surrounds energized conductors. It is ideal for tracing
live wiring connections, locating wiring breakage and to
distinguish between live or earth connections.
