NCV Test
• The reading hold mode can hold the current
reading on the display by short pressing
the HOLD key. Short press the HOLD key to
switch the measuring function, or to exit the
reading hold mode.
• Press the key for 2 seconds to turn the
backlight on or o.
• Turn the range switch to Afor current meas-
urement, and press the SEL key to switch to
AC or DC according to the current job.
• Hold the trigger to open the meter jaws, and
clamp a wire of the line to be measured in
the centre of the clamp head.
• When both jaws are completely closed, the
meter will display the measured current
value.
• Only a single wire can be clamped for
measurement at one time. It is impossible to
accurately measure current from two wires
simultaneously.
• The maximum measurable current is 100A.
• Resistance Measurement; press the SEL
key to M, which is the automatic switch for
automatic range k/M measurement.
• Continuity Measurement; If the resistance
of the tested object is less than approx. 50Ω,
the indicating light (red light) of the meter
will remain on, and the buzzer will sound
continuously.
• Diode Measurement; Press SEL key to
• When measuring normal diode, the meter
will display the forward voltage drop of the
diode — Normal 0.5V to 0.8V forward voltage
drop.
• If the meter is not used within 15 minutes
after starting, the unit will shut down auto-
matically and enter sleep mode.
• Press the HOLD button under the Automatic
Shutdown mode to turn the meter on.
• This meter adopts automatic range detec-
tion. When measuring AC/DC voltage,
resistance, and capacitance, the values will
automatically be displayed on the screen.
• Turn the switch to the setting, press the
SEL key to choose corresponding functions.
Plug the red and black test pens to the INPUT
socket and COM socket respectively.
• Capacitance Measurement; the capaci-
tance range of the meter is 200nF, 2uF, 20uF,
200uF, 2000uF.
• Press the SEL key to nF; which is the auto-
matic switch for automatic range nF/F meas-
urements.
• Turn the rotary switch to the posi-
tion, and short press the SEL key to switch
between AC or DC voltage.
• Plug both the black and red test pen to the
COM socket and INPUT socket respectively.
• Connect the test pen to the circuit that you
want to test.
• Switch to the NCV key and move the clamp
head close to the conductor. By detecting
the signal strength, the meter judges the
strength of the tested voltage. The screen
then displays ----- red indicating light, and
the buzzer will emit alarm sounds of dierent
frequencies.

NOTE
In the mV range of DC and AC, even if
there is no test pen input or connection,
the meter will display a numerical
value. In this case, if the “V” and “COM”
terminals are short-circuited, the meter
will display zero, which is normal.
The AC/DC voltage range of this meter:
Gear 2V, 20V, 200V, 600V
Gear 2V, 20V, 200V, 600V
The actual value of the resistance may
dier from that measured on the circuit.
When the meter measures an open
circuit, or the measured resistance value
is too big, the screen will display “OL”
(Overload) which means the measured
value is beyond the range.
To ensure the readings are accurate,
short press the ZERO key under the
DC current mode, which will clear
the low number of the DC caused by
electromagnetic interference.
The Capacitor should be fully
discharged before measuring the
capacitance. Therefore it may take
some time to stabilise the reading, as
the capacitor needs to be charged.
Temperature Measurement
• When setting the range, switch to the posi-
tion, the meter will automatically measure
and show the current environmental temper-
ature. Pressing the SEL key will switch to °F.
• To measure the temperature of an object
or liquid, insert the red plug of the K-Type
thermocouple into the INPUT socket and the
black plug into the COM socket, then ensure
the thermocouple probe comes into contact
with the test area.
