Even if there is no alarm indication, the voltage may
still be present. Do not rely on the non-contact voltage
to determine whether a wire has a voltage.
Probe operation may be influenced by socket design,
type of insulation thickness, etc.
In NCV detection mode, the meter does not measure
voltage, resistance, and current simultaneously.

electric current measurement
Ac current and AC current frequency measurement
Automatic mode measurement:
1) Hold the trigger, open the clamp head, and clamp a wire of the
tested line in the clamp.
2) When the measured signal >1A, the instrument main display
screen displays the measured current value
(Note: only when the current value is >35A,the instrument
auxiliary display will display its frequency value)
Manual mode measurement:
1) Press SEL key to switch to AC current, hold the trigger, open
the clamp head,
Clamp one of the wires of the line under test in the clamp.
2) When the measured signal > 0.2a, the main display screen
of the instrument will display the measured Current value.

Dc current measurement
Manual mode measurement:
1) Press SEL key to switch to DC current mode.
2) The front end of the clamp head is close to the measured
wire. Press the REL button to make its base close to zero,
Vice display character.
3) Hold the trigger, open the clamp head, and clamp a wire of
the tested line in the clamp.
4) When the measured signal > 0.2a, the main display screen
of the instrument shows the measured current value.
Note: To get an accurate reading, press the "REL" key
to reset the meter to zero before measuring.

Dc voltage measurement
Connect the test pen to the test signal.
When the test signal is <600mV,
the instrument will display the current

when the test signal is >600mV,
the instrument will display "OL".
Connect the test pen to the signal being tested. When the

5. Maintenance
5.1 Change battery
Warning
Before opening battery cover of the
instrument, remove the pens from the circuit being
measured, to avoid electric shock.
1) If symbol "
" appears, it indicates to change the
battery.
2) Unfasten bolts on battery cover of instrument and
remove the cover.
3) Change the old battery.
4) Place the battery cover.
Do not reverse battery polarity.
17
5.2 Change pens
Warning
When changing the pen, it is required to
replace with an identical pen or a pen of the same
level.
The pen must be in good condition, and level
of the pens is: 1000V 10A.
If insulation layer of the pen is damaged, or metal wire
of the lead exposes, it is required to change the pen.
