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.
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.
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.

4) OPERA ION
CAUTION: Before and after hazardous voltage measurements, test the voltage
funct on on a known source such as l ne voltage to determ ne proper meter funct on ng.
DC Voltage, AC Voltage, Hz Frequency functions
Set slide switch to Voltage function position. Inputs are made through the test leads
terminals. For Models 063 & 065, slide switch on defaults at AC voltage. Press
SELEC button momentarily to select DC voltage. For Models 061& 062, separate
ACV & DCV slide switch positions are being used.
Press the Hz button momentarily to activate Hz Frequency. The Hz trigger level is
determined by the selected function range from where the Hz function is activated. In
ACV function, activating the Hz function during significant measurements can get the
most appropriate trigger level to avoid electrical noises in most cases. Electrical noise
may cause unstable Hz reading. Activating the Hz function at AC 4.000V range (before
making significant measurements) can get lower trigger level (higher sensitivity). Hz
reading may show zero when the sensitivity is insufficient.

5
Note: DC 400.0mV range is designed with 1000MΩ high input impedance for least
current drain in measuring small signals, and can cope better with most commercially
available voltage output transducers/adapters. The non zero display reading is normal
when the meter inputs are open circuit, which will not affect actual measurement
accuracy. The meter will show close to zero readings when the inputs are shorted.
Open input is actually a floating condition, which is not a zero volt input condition.
ACA & DCA Current clamp-on function
Inputs are made through the clamp jaws for non invasive ACA & DCA current
measurements.
CAUTION (Appl cat on and removal of the Clamp-on meter)
Press the jaw trigger and clamp the jaws around only one single conductor of a circuit
for load current measurement. Make sure the jaws are completely closed, or else it will
introduce measurement errors. Enclosing more than one conductor of a circuit will
result in differential current measurement (like identifying leakage current). Locate the
conductor(s) at the Jaws center as much as possible to get the best measuring
accuracy. The jaw “+” mark indicates current flow direction on DCA positive readings.

6
For removal, press the jaw trigger and remove the jaws from the conductor(s).
Note: In DCA measurements, hysteresis of the jaws (after measuring high DC currents)
may introduce non zero residual readings. Relative Zero mode should be used
each time to offset the residual readings, if any, for more accurate measurements.
Adjacent current carrying devices such as transformers, motors and conductor wires
will affect measurement accuracy. Keep the jaws away from them as much as possible
to minimize influence.
Ω
ΩΩ
Ω Resistance, and Continuity functions
CAUTION
Using Resistance, Continuity or Diode function in a live circuit will produce false results
and may damage the instrument. In many cases the suspected component must be
disconnected from the circuit to obtain an accurate measurement reading
Inputs are made through the test leads terminals. Slide switch on defaults at Ω. Press
SELEC button momentarily to select Continuity function which is convenient for
checking wiring connections and operation of switches. A continuous beep tone
indicates a complete wire.

7
Diode test function
Inputs are made through the test leads terminals. Slide switch on defaults at Ω. Press
SELEC button momentarily 2 times to select 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).
Capacitance function
Inputs are made through the test leads terminals. Slide switch on defaults at Ω. Press
SELEC button momentarily 3 times to select Capacitance function. Relative zero
mode can be used to zero out the parasitic capacitance of the leads and the internal
protection circuitry of the meter when measuring low capacitance in the order of Pico
Farad (pF).
CAUTION
Discharge capacitors before making any measurement. Large value capacitors should
be discharged through an appropriate resistance load

8
emperature function (Model 065 & 063 only)
Be sure to insert the banana plug type K temperature bead probe Bkp60 with correct
polarities. Slide switch on defaults at degree C (Celsius). Press SELEC button
momentarily to select degree F (Fahrenheit). You can also use a plug adapter Bkb32
(Optional purchase) with banana pins to type K socket to adapt other type K standard
mini plug temperature probes.
HOLD
The Hold feature freezes the display for later viewing. Press the HOLD button
momentarily to toggle to the Hold feature. The annunciator “ ” turns on.
MAX
The max feature compares and displays the measured maximum value as fast as

9
30ms with auto ranging capability. It allows the meter to capture in rush currents in
current functions. Press and hold the MAX button for 1 second or more to toggle to
the max feature. The annunciators “MAX” and “ ” turn on.
Relative Zero mode
Relative Zero mode allows the user to offset the meter consecutive measurements
with the displaying reading as the reference value. The display will now show readings
relative to the stored reference value. That is, display = reading stored value. Press
the button momentarily to toggle to the relative zero mode. The annunciator “ ”
turns on. The meter also enters manual ranging mode where available. The
annunciator “ ” turns off.
Display Backlight (Model 065 & 062 only)
Press the SELEC button for 1 second or more to toggle the display backlight on and
off.
Auto Power Off (APO)
When the meter is on, the Auto Power Off (APO) feature will switch the meter to sleep
mode automatically after approximately 30 minutes of neither slide switch nor push
button operations to extend battery life. To wake up the meter from APO, press any
push button momentarily or set the slide switch to the OFF position and then slide back
on again. Always set the slide switch to the OFF position manually when the meter is
not in use.
5) MAIN ENANCE
WARNING
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.
rouble Shooting
If the instrument fails to operate, check batteries and test leads etc., and replace as
necessary. Double check operating procedure as described in this user’s manual
If the instrument voltage resistance input terminal has subjected to high voltage
transient (caused by lightning or switching surge to the system) by accident or
abnormal conditions of operation, the series fusible resistors will be blown off (become
high impedance) like fuses to protect the user and the instrument. Most measuring

10
functions through this terminal will then be open circuit. The series fusible resistors
and the spark gaps should then be replaced by qualified technician. Refer to the
LIMITED WARRANTY section for obtaining warranty or repairing service.
Cleaning and Storage
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 60 days, remove
the batteries and store them separately
Battery replacement
The meter uses standard 1.5V AAA Size (NEDA 24G or IEC R03) battery X 2; or 1.5V
AAA Size (NEDA 24A or IEC LR03) alkaline 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.
