3. USE
3.1 First use
Place the batteries in the device as follows:
1. Use a screwdriver, unscrew all the battery cover screws on the back of the meter.
2. Place the batteries in the casing, respect polarity.
3. Screw back battery cover screws.
It is recommended to follow this procedure when you use the
meter for the first time, or after long time without use:
• Start the meter, make sure that all segments are
displayed.
• Check that on Continuity position, and without any
input the meter display OL.
• Take out both cords and short circuit, the beeper
should sound.
• Turn the rotary switch on V and check a known
voltage (for example a battery) and make sure
voltage is correct.
• When all the steps above are correct, you can
start to use the meter.

3.2 Backlight and Torch light
When pressing the
key for more than 2s, both LCD backlight (blue) and torch
light (white) will light up.
Press again
for more than 2s to shutdown the backlight.
On NCV position the backlight will blink red if AC live voltage is detected.
3.3 Measuring AC or DC voltages
The meter measures AC or DC voltage. To minimize risk when
measuring an unknown voltage, make sure to measure both
AC and DC voltage
1. Turn the rotary switch to
(10 MΩ),
(500 kΩ).
2. Toggle between AC or DC voltage measurement by pressing the yellow button (in
VlowZ: only AC measurement available).
3. Connect the red test lead to the + terminal and the black test lead to the COM
terminal.
4. Measure the voltage by touching the probes to the desired test points of the circuit:
Digital Multimeter VAC or DC
Digital Multimeter VLowZ
To avoid to measure ghost voltage, choose
, impedance of the DMM is lower
in Low Z (500 kΩ).
