3.2 Measurement guidelines
3.2.1 AC Voltage and DC Voltage Measurement
The meter provides DC voltage measuring ranges as follows: 200.0mV,
2.000V, 20.00V, 200.0V and 600V, and AC voltage measuring ranges:
200.0V and 600V.
To avoid any electric shock and/or damage to the meter, do
not attempt a voltage measurement if the voltage (valid value)
is over 600V DC or AC current.
To avoid any electric shock and/or damage to the meter, don't
attempt to impose between any public terminal and ground
any voltage whose valid value is over 600V for DC or AC
current.

Turn the rotary switch to the position
～
V or V.

Connect the test lead in black and test lead in red to COM input
socket and V input socket respectively.

Use another two ends of the test lead to measure the voltage of the
circuit to be measured. (In parallel connection with the circuit to be
measured)

Read the measured voltage value on LCD screen. When DC voltage
measurement is attempted, the display unit will show the voltage
polarity of the circuit connected to the pen-shaped meter in red.

To avoid the meter or the measured equipment from damage,
do not attempt a resistance measurement unless the operator
has already cut off all power sources for the circuit to be
measured and fully discharged all high-voltage capacitors.
