in this manual.
• Keep your fingers behind the protection ring on the test
probes when using the test leads.
• Change the battery when the symbol appears to
avoid incorrect reading.

5. BUTTON INSTRUCTION
5-1 HOLD & LPF Function
The meter has a data hold feature that will retain the
measured value on the LCD screen. Press the “HOLD”
button momentarily to retain the measured value. Press the
“HOLD” button again or power the meter off and back on
to resume normal operation.
To activate the Low Pass Filter (LPF) feature, press and hold
the “LPF” button until the symbol displays. Press and hold
the “LPF” button for 2 seconds to deactivate the “LPF”
feature and resume normal operation.
The Cut-Off frequency of the low pass filter is about 160Hz
with attenuation characteristic of approx. -24dB/octave.
Note: the LPF function operates on the AC A
and AC mA ranges.
5-2 PEAK Hold and /ΩFunction Selection
Press “PEAK” button to enter the “PEAK” mode, the meter
records the peak maximum value. Press the “PEAK” button
again, to exit the peak mode.
When you turn the rotary switch to the Ohms/Continuity
Test position, press the “PEAK” button to select continuity
test with buzzer.
5-3 ZERO Function
Press “ZERO” button to enter the “ZERO” mode, ZERO
Indicator will appear and the display will ZERO. The
reading is stored as reference value for the subsequent
measurement.
Press the “ZERO” button again, to exit the ZERO mode.

5-4 BACKLIGHT Function
When the “☼“ button is pressed, the LCD display backlight
will be turned on. Press the button again to turn the
backlight off. If the button is not pressed again then the
backlight will be automatically turned off in about 30
seconds after it’s turned on.
6. MEASURING INSTRUCTION
6-1 ACA, ACmA Measurement:
(1) Set the range selector switch to the desired position.
The current to be measured should be within the
measuring range.
(2) Normal measurement (see Fig. 1):
Using the trigger, open the clamp meter jaw and clamp
around the conductor. Make sure that the conductor
is positioned in the center and that the flow of current
matches the arrows located on the jaws of the clamp meter.
The display will show the value of the measurement being
taken. Earth leakage current or any small AC current that
flows through a ground wire can also be measured
by this method.
NOTE: Keeping the cable in the center of the clamp will
return more accurate test results when making current
measurements. Zero meter to accurately measure low
milliamp circuits.
(3) Measuring out of balance leakage current (see Fig. 2):
Disconnect the test leads from the meter. Clamp the
jaw around all conductors except the ground wire. The
measured imbalance current value is shown on the display.
If the display is not giving a steady and consistent reading,
press the HOLD button and read the display after the
clamp is removed from the conductors.

6-2 ACV Measurement:
Turn the dial to the ṽrange. Connect the red test lead to
the “+” terminal and the black lead to the “COM” terminal.
Place the red and black test leads at both the positive and
negative points to be measured. The display will show the
value of the measurement being taken.
WARNING!
Maximum Input Voltage is 600V AC/DC. Do not
attempt to take any voltage measurement that may
exceed this maximum to avoid Electrical Shock hazard
and/or damage to this instrument.

6-3 DCV Measurement:
Turn the dial to the Vrange. Connect the red test lead to
the “+” terminal and the black lead to the “COM” terminal.
Place the red and black test leads at both the positive and
negative points to be measured. The display will show the
value of the measurement being taken.
6-4 Continuity Test with Buzzer:
Turn the dial to the Ωrange. Connect the red test lead to
the “+” terminal and the black lead to the “COM” terminal.
Place the red and black test leads at both the positive and
negative points to be measured. The buzzer will sound when
the resistance is less than 45 Ω.
NOTE:
When measuring continuity, all power to the circuit or cable
being tested MUST be turned off to prevent damage to the
user or the clamp meter.

6-5 Resistance Measurement:
Turn the dial to the Ωrange. Connect the red test
lead to the “+” terminal and the black lead to the “COM”
terminal. Place the red and black test leads at both the
positive and negative points to be measured. The display
will show the resistance value of the measurement being
taken on the display.
NOTE:
When measuring resistance, the circuit should be powered
off and all capacitors should be completely discharged
prior to testing.

7. CHANGING THE BATTERY
Replace the batteries when a low battery symbol is
displayed on the LCD screen. When the battery is
completely exhausted, the display will appear blank
and no symbol will be shown. Rotate the dial to the “OFF”
position and remove the test leads. Remove the cover using a
screwdriver. Replace the batteries. Use two new 1.5V (AAA)
batteries. Reinstall the door and tighten the screw
to secure the cover.
NOTE: Remove the batteries if the mter is not going to be
used for an extended period of time. The meter should be
stored in a cool, dry location.
8. MAINTENANCE
8-1 Cleaning:
Use only a soft cloth dampened with water or
neutral detergent for cleaning the meter. Do not use
abrasives, solvents or harsh chemicals. Allow to dry
thoroughly before use.
WARNING!
Before opening the meter, disconnect both test leads.
Never use the meter unless the battery cover is in place
and the screw is tightened.

7. CAMBIO DE BATERÍA
Reemplace las baterías cuando en la pantalla LCD aparece
el símbolo de batería baja . Una vez que la batería se
agota completamente, la pantalla aparece en blanco y no
se muestra ningún símbolo. Gire el dial a la posición “OFF”
(apagado) y saque los cables de prueba. Saque la cubierta
con un destornillador. Reemplace las baterías. Use dos
baterías de 1.5 V (AAA) nuevas. Vuelva a colocar la puerta
y ajuste el tornillo para asegurar la cubierta.
NOTA: Saque las baterías si no usará el medidor durante
un período prolongado. Deberá guardar el medidor en un
lugar fresco y seco.
8. MANTENIMIENTO
8-1 Limpieza:
Use solo una tela suave humedecida con agua o detergente
neutro para limpiar el medidor. No use abrasivos,
disolventes o productos químicos agresivos. Deje secar
completamente antes del uso.
¡ADVERTENCIA!
Antes de abrir el amperímetro, desconecte ambos
conductores de prueba. Nunca use el amperímetro sin la
cubierta de la batería en su lugar y el tornillo apretado.
