4. Preparation

4.1 Power on / Self-diagnostic
(1) Press the "ON/OFF" button on both main
probe and 2nd probe simultaneously,
then shorting the two metal probes. The
power shall automatically turn on, and
the equipment start self-diagnostic func-
tion.

CAUTION
(2) Do not operate the equipment if any
abnormal appear during self-diagnostic.
(3) All indicators on LCD shall show up, and
buzzer shall buzzing during the normal
self-diagnostic.
(4) L CD will flash 5 times when battery
power is lower than 2.2 ± 0.1V. Please
change the battery.
4.2 Trouble shooting
If any of the following happened, please
open the battery case and close it again af-
ter 5 seconds. Please do self-diagnostic after
closing the case again.
(1) Cannot self-diagnostic before or after
the operation of the equipment.
(2) Cannot auto power off.
5. Measurement
CAUTION
Please read the manual carefully.
Please do self-diagnostic to insure the
LCD and buzzer function properly.
Please conform the equipment with a
known voltage source.
Please place the hand behind the barrier.
As the equipment has higher impedance
(about 300k Ω), capacitor and inductor
voltage may indicate.
Operating Instruction
5.1 AC / DC Polarity Measurement
(on 2nd probe)
(1) Connecting two probes to two ports of
the voltage source.
(2) Without pressing any button, the
polarity of AC / DC (24V – 1000V) will be
indicated on the 2nd test probe.
(3) AC: both polarity lights up. (+) DC: DC+
lights up. (-) DC: DC- lights up.
(4) The direction of the main probe will
determine (+)DC or (–)DC. If main probe
is on the positive port, DC+ lights up,
and vice versa.
(5) This function will be canceled if any one
of the ON / OFF button is pressed.

5.2 Voltage Measurement

5.2.1 Voltage And Polarity
(1) Connecting two probes to two ports of
the voltage source.
(2) Press two ON / OFF buttons on two pro-
bes at same time. Voltage and polarity
will be displayed on the LCD. ( DC6 –
1000V; AC24 – 1000V; AC / +DC / -DC ).
(3) The direction of the main probe will
determine DC+ or DC-. If main probe is
on the positive port, DC+ lights up, and
vice versa.

CAUTION
(4) If only one of the buttons has pressed,
error voltage value AC 23V – AC 55V will
be displayed on the LCD when voltage
is greater than AC 470V.
5.2.2 High Voltage indication
LCD will display „ " when voltage source
≥ 100VAC/ VDC.
5.2.3 Phase Rotation
(1) Phase rotation measurement is only for 3
phase ( 4 lines ) system. Please using the
right hand hold the main probe handle
(behind the barrier) properly during the
measurement (because one of the sen-
sing area is on the main probe handle).
(2) LCD will display voltage between phases.
(3) If the rotation is clockwise, LCD will
display "R" .
