4.6. AC/DC Current Measurement
1
）
Hold the trigger, open the clamp head and clamp one cable
of the measured circuit.
2) When measured signal >0.2A (AC), the main LCD of the
meter displays the measured current value, the vice LCD
displays current frequency (Note: only when AC current
value >2A could the meter displays its frequency value).
3) When measured signal >0.3A (DC), the main LCD of the
meter display the measured current value.
4.7. DC Voltage Measurement

）
Connect the pen-shaped meter to the measured signal,
when the measured signal >=0.5V, will the meter display
current measuring DC voltage value. When measured signal
is <0.5V, the meter will be default as resistance value,
displays the ohm of the measured signal.
4.8. AC Voltage Measurement
1
）
Connect the pen-shaped meter to the measured signal,
when the measured signal >=1.0V, will the main LCD of the
meter display current measuring AC voltage value, and the
vice LCD will display the frequency value of the voltage.
When measured signal is <1.0V, the meter will be default as
resistance value, displays the ohm of the measured signal.
4.9. Resistance Measurement

）
Connect the pen-shaped meter to the measured resistan-
ce, when the measured resistance >10MΩ, the meter will
display----, when the measured resistance is less than 50Ω,
the meter buzzer will send out alarm sound.
4.10. Measure AC current (or DC current) and AC voltage
at the same time

）
Hold the trigger, open the clamp head and clamp one cable
of the measured circuit, when the measured signal >0.2A
(
AC current 0.2A , DC current 0.3A), the meter vice LCD will
display measured current value.

Connect the pen-shaped meter to the measured signal,
when the measured signal >=1.0V, the meter main LCD will
display current measured AC voltage value. When measu-
red signal is <1.0V, the meter will be default as resistance
value, displays the ohm of the measured signal.
4.11. Measure AC current and DC voltage at the same
time

Hold the trigger, open the clamp head and clamp one cable
of the measured circuit, when the measured signal >0.2A
(
AC current 0.2A , DC current 0.3A), the meter vice LCD will
display measured current value.

measured DC signal <0.5V, the meter will be default as
resistance value, displays the ohm of the measured signal.
4.12. Measure AC current(or DC current) and resistance at
the same time

than 50Ω, the meter buzzer will send out alarm sound.
5. Maintenance
5.1. Replace Battery
Warnings
Before opening the battery cover of the meter, the pen-shape
meter shall be moved from the measuring circuit first to
prevent the risk of electric shock.
1) If “ ” symbol appears, it means the battery shall be
replaced.
2) Screw the fastening screws of the meter battery cover and
move away.
3) Replace the old battery.
4) Install the battery cover as previous.
Note:
Do not violate the battery polarity.
5.2. Replace Pen-shaped Meter
Warnings
When replacing the pen-shaped meter, the new ones shall be
of the same or in eqaul level. The pen-shaped meter shall be
in good condition, pen-shaped meter level: 1000V 10A.
If the insulation layer of the pen-shaped meter is damaged,
such as the metal wire of the cable is exposed, then it shall be
replaced.
