I. SAFETY :
This manual contains information and warnings that must be
followed for operating the instrument safely and maintaining the
instrument in a safe operating condition. If the instrument is used in
manner not specified by the manufacturer, the protection provided
by the instrument may be impaired.
The meter protection rating, against the users, is double insulation
per UL/IEC/EN61010-1 Ed. 3, IEC/EN61010-2-033 Ed. 1, CAN/
CSA C22.2 No. 61010-1 Ed. 3, IEC/EN61010-2-032 Ed. 2 & IEC/
EN61010-031 Ed. 1.1 :
Measurement Category III 600V & Category IV 300V AC & DC.
Per IEC610-1 (2010) OVERVOLTAGE CATEGORY
OVERVOLTAGE CATEGORY II (CAT II) is for equipment intended
to be supplied from the building wiring. It applies both to plug-
connected equipment and to PERMANENTLY CONNECTED
EQUIPMENT.
OVERVOLTAGE CATEGORY III (CAT III) is for equipment intended
to form part of a building wiring installation. Such equipment
includes socket outlets, fuse panels, and some MAINS installation
control equipment.
OVERVOLTAGE CATEGORY IV (CAT IV) is for equipment installed
at or near the origin of the electrical supply to a building, between
the building entrance and the main distribution board. Such
equipment may include electricity tariff meters and primary over
current protection devices.
Terms in this manual :
WARNING Identifies conditions and actions that could result in
serious injury or even death to the user.
CAUTION Identifies conditions and actions that could cause
damage or malfunction in the instrument.

® ®

WARNING :
To reduce the risk of fire or electric shock, do not expose this product
to rain or moisture. The meter is intended only for indoor use.
To avoid electrical shock hazard, observe the proper safety
precautions when working with voltages above 60 VDC or 30 VAC
rms. These voltage levels pose a potential shock hazard to the user.
Before and after hazardous voltage measurements test the voltage
function on a known source such as line voltage to determine proper
meter functioning.
Keep your hands/fingers behind the hand/finger barriers (of the meter
and the test leads) that indicate the limits of safe access of the hand-
held part during measurement. Inspect test leads, connectors and
probes for damaged insulation or exposed metal before using the
instrument. If any defects are found, replace them immediately. Only
use the test lead provided with the equipment or UL Listed Probe
Assembly rated CAT III 600V or better.
This Clamp-on meter is designed to 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.
CAUTION :
Disconnect the test leads from the test points before changing meter
functions.

CAUTION & WARNING for Non-Invasive (Clamp-on)
Current Measurements :
CAUTION :
(Application and Removal of the Clamp-on Jaws) For non-invasive
current measurements, press the jaw trigger and clamp the jaws
around conductor(s) of only one single pole of a circuit for load
current measurement. Make sure the jaws are completely closed, or
else it will introduce measurement errors. Enclosing conductor(s) of
more than one pole of a circuit may result in differential current (like
identifying leakage current) measurement. Align the conductor(s) to
TM
the Jaws center indicators (Regular or AmpTip 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
conductor(s).
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 :
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.

Electric Field EF-Detection
The meter displays “EF” when it is ready. Signal strength is indicated
as a series of bar-graph segments on the display together with
variable beep tones.
vNon-Contact EF-Detection : An antenna is located along the
top-right end of the stationary clamp jaw, which detects electric
field that surround energized conductors. It is ideal for tracing
live wiring connections, locating wiring breakage and to
distinguish between live or earth connections.
vProbe-Contact EF-Detection : For more precise indication of
live wires, such as distinguishing between Live and Ground
connections, use one single probe to test via terminal COM for
direct contact EF-Detection with best sensitivity.

Note : When using diode test function, normal forward voltage drop
(forward biased) for a good silicon diode is between 0.400V to
0.900V. A reading higher than that indicates a leaky diode (defective).
A zero reading indicates a shorted diode (defective). An OL indicates
an open diode (defective). Reverse the test leads connections
(reverse biased) across the diode. The digital display shows OL if the
diode is good. Any other readings indicate the diode is resistive or
shorted (defective).
CAUTION :
Using Resistance, Continuity or Diode function in a live circuit will
produce false results and may damage the meter. In many cases
the suspected component(s) must be disconnected from the circuit
to obtain an accurate measurement reading.
W Resistance, Continuity & Diode functions :
Inputs are made through the test lead terminals COM/+.
Defaults at W Resistance. Press SELECT button momentarily to
select the subject functions in sequence.

The Complementary Beeper feature is selected in Power-up option.
Press and hold the REC button while turning the meter on to enable.
If the segments indicate a clockwise movement, the beeper sounds
a single long beep per segment cycle. If the segments indicate a
counter clockwise movement, the beeper sounds 3 short beeps per
segment cycle.
USING THE COMPLEMENTARY BEEPER FEATURE :
HOLD :
Hold feature freezes the display for later view. LCD “ ” turns on.
Press the HOLD button momentarily to toggle the hold feature.
H
RECORD MODE :
Press REC button momentarily to activate MAX/MIN/AVG recording
mode. LCD “ ” & “MAX MIN AVG” turn on. The meter beeps when
new MAX (maximum) or MIN (minimum) reading is updated. AVG
(Average) reading is calculated over time. Press the button
momentarily to read the MAX, MIN and AVG reading in sequence.
Press the button for 1 second or more to exit this mode. Auto-
Power-Off is disabled automatically in this mode.

In other words, the meter will intelligently avoid entering the APO
mode when it is under normal measurements. To wake up the
meter from APO, press the SELECT button momentarily and
release, or turn the rotary switch OFF and then back on. Always turn
the rotary switch to the OFF position when the meter is not in use.
V. MAINTENANCE :
To avoid electrical shock, disconnect the meter from any circuit,
remove the test leads from the input jacks and turn OFF the meter
before opening the case. Do not operate with open case.
WARNING :
If the instrument fails to operate, check batteries and test leads etc.,
and replace as necessary. Double check operating procedure as
described in this manual.
Trouble Shooting :
If the instrument voltage-resistance input terminal has subjected to
high voltage transient (caused by lightning or switching surge to the
system under test) by accident or abnormal conditions of operation,
the protective impedance components in series might be blown off
(become high impedance) like open fuses to protect the user and
the instrument. Most measuring functions through this terminal
might then be open circuit. Such components should only be
replaced by qualified technician. Refer to the WARRANTY section
for obtaining warranty or repairing service.
Intelligent Auto-Power-Off (APO) :
The Auto-Power-Off (APO) mode turn the meter off automatically to
extend battery life after approximately 32 minutes of no specified
activities, where applicable :
1. Rotary switch or push button operations.
2. Significant measuring readings of above 8.5% of ranges.
3. Non-OL readings for Resistance, Continuity or Diode function.
4. Non-zero readings for Hz function.
5. Significant movement indication as in Phase Rotation functions.
Periodically wipe the case with a damp cloth and mild detergent; do
not use abrasives or solvents. If the meter is not to be used for
periods of longer than 30 days, remove the batteries and store them
separately.
Cleaning and Storage :
Battery replacement :
The meter uses standard 1.5V AAA Size (IEC R03) battery X 2.
Loosen the 2 captive screws from the battery cover case. Lift the
battery cover case. Replace the batteries. Replace battery cover
case. Re-fasten the screws.
