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
Press the clamp, open the clamp mouth and clamp one of the
wires under test.
When the measured signal is greater than 0.2a, the meter display
displays the current value and frequency value
of the measured conductor.
(Note: The meter can display the
frequency value only when the current
value is greater than 35A)
Dc current measurement
Press the clamp, open the clamp mouth and clamp one of the
wires under test.
When the measured signal is
greater than 0.2a, the meter display
displays the current value and
frequency value of the measured
conductor.
(Test instrument with dc current function)

13
Connect the test pen to the signal
being tested.
When the measured AC signal is
greater than 0.5V, the display
displays the voltage and
frequency values.
When the measured
AC signal <0.5V, the instrument
default resistance value, display
the measured signal internal
resistance value.
Press SEL button to dc voltage mV,
the instrument shows mV
Dc voltage measurement
Connect the test pen to the test signal.
When the test signal is <600mV,
the instrument will display the current
dc voltage value under test;
when the test signal is >600mV,
the instrument will display "OL".
Connect the test pen to the signal being tested. When the
measured DC signal is greater than 0.5V, the display voltage
value. When the measured DC signal is <0.5V, the instrument
uses the default resistance value and displays the resistance
value of the measured signal.

14
Press SEL to enable the mV function. Instrument display mV
Connect the meter and meter pen to the signal under test.
When the measured signal is less than 600mV,
the meter displays the measured current
dc voltage value.
When the measurement signal
is > 600mV, the instrument
displays "OL".
Ac voltage measurement
resistance measurement
Connect the test pen to the resistance to be measured.
The main display of the instrument will display the measured
resistance value.
When the measurement resistance
is less than 50 ,
the instrument buzzer
sound alarm, indicator
light on.

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.

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.
