WARNING: If the flexible tester is used in a manner
Not specified by the manufacturer, the protection
Provided by the clamp meter may be impaired.
WARNING
Don’t use the flexible current probe before you read
the following instructions.
1. Don’t install the flexible current probe around bare conductors carrying a voltage from 30V to 600V unless
you are wearing protective clothing and glove suitable for high-voltage work.
2. Always inspect and check any damage of the current probe assembly before usage. Don’t use the

1. Coupling Assembly
2. Flexible Loop
Open the coupling connector and circle around the conductors. Then re-connect the coupling connector.
3. 50/60 Hz button
Press this button to select nominal frequency (50 or 60Hz).
It is also used to decrement the order of harmonics or CT ratio.
If this button is hold when turning on power, the tester can perform measurement of phase sequence instead of phase
angle in the balanced 3Φ power system.
4. LCD
This is a 4+4 digit Liquid Crystal Display. Function symbols, units, sign, decimal points, low battery symbols, max, min
symbols, peak and harmonic symbols are included
5. MAX/MIN/HOLD/PEAK
In the measurement of A, or V, press this button to perform function of MAXIMUM, MINIMUM, HOLD or PEAK.
6. Sliding Switch
This is used to turn the power on and select measurement of current, voltage or power.
7. COM Terminal
This terminal is used as common reference input.
8. V Input Terminal
This terminal is used as input for voltage and power measurements.
9. Battery Cover
III. OPERATING INSTRUCTIONS
III.1. Measurement of ACA
NOTE:
1. Set the sliding switch at the A position.
2. If the peak value of the input AC current is greater than the maximum value of the range, then symbol of OL will be
displayed.

WARNING: Always wear appropriate gloves in operation..
WARNING: Make sure that all the test leads are disconnected from the meter's terminals for current measurement.
III.1.1. True RMS value of AC Current
a. Set the sliding switch at A..
b. Connect the flexible probe around the conductor. Keep the probe coupling more than 25mm away from the
conductor.

c. Read the measured value from the LCD display. The actually measured frequency will be displayed in the upper
LCD.
NOTE: If the true RMS value is less than 3A, the frequency of the signal will be displayed as 0 (Please refer to the
following figure.
III.1.2. HOLD, MAX, MIN and PEAK of AC Current.
a. Set the sliding switch at A.
b. Connect the flexible probe around the conductor. Keep the probe coupling more than 25mm away from the
conductor.
c. The measured value from the LCD display. If the HOLD button is pressed, the symbol of “HOLD”, “MAX”, “MIN”
or “PEAK” will be shown in LCD alternatively. And the value of the HOLD, MAX, MIN or PEAK function will be
displayed in LCD alternatively.
d. To return to the display of current measurement, hold the HOLD button for more than 2 seconds.
NOTE: The PEAK function displays the maximum value of the input waveform. The sampling time for the PEAK
function is 39 μs (50Hz) or 33μs (60Hz). The HOLD, MAX, or MIN function displays the true RMS value.
III.2 Measurement of ACV
NOTE: If the peak value of the input AC voltage is greater than the maximum value of the range, then symbol of OL
will be displayed.
WARNING: Maximum input for ACV is 600. Do not attempt to take any voltage measurement that exceeds the
limits. Exceeding the limits could cause electrical shock and damage to the clamp meter.

III.2.1. True RMS value of AC Voltage
a. Set the sliding switch at position V.
b. Insert the test leads into the input jack. Connect the test prods of the test leads in PARALLEL to the circuit to
be measured.
c. Read the measured RMS value from the LCD display.
NOTE: If the true RMS value is less than 10V, the frequency of the signal will be displayed as 0 (Please refer to the
following figure).

III.2.2. HOLD, MAX, MIN and PEAK value of AC Voltage
a. Set the sliding switch at position V. Then select the correct fundamental frequency by pressing the 50/60 Hz
button.
b. Insert the test leads into the input jack. Connect the test prods of the test leads in PARALLEL to the circuit to
be measured.
c. The measured value is displayed in the LCD display. If the HOLD button is pressed, the symbol of “HOLD”,
“MAX”, “MIN” or “PEAK” will be shown in LCD alternatively. And the value of the HOLD, MAX, MIN or PEAK
function will be displayed in LCD alternatively.
d. To return to the display of current measurement, hold the HOLD button for more than 2 seconds.
NOTE: The PEAK function displays the maximum value of the input waveform. The sampling time for the PEAK function is
39μs (50Hz) or 33μs (60Hz). The HOLD, MAX, or MIN function displays the true RMS value.
III.3 Disable Auto Power Off
The tester has an auto-power-off function. The tester will turn the power off after power is turned on for 15 minutes.
To disable the auto power off function, hold the HOLD button, and then turn the power on.
IV. FIX THE NOMINAL FREQUENCY
When the power is turned on, the tester will measure the frequency of signal automatically. If users wish to fix the
measuring frequency at 50 or 60 Hz, they can hold the 50/60Hz button and turn the power on.
