4. Preparation
4.1 Power on / Self-diagnostic
(1) Press the "ON/OFF" button on both main probe and
2 nd probe simultaneously, then shorting the two metal
probes. The power shall automatically turn on, and the
equipment start self-diagnostic function.
(2) CAUTION: 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) LCD 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 after 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 300kΩ),
capacitor and inductor voltage may indicate.
5.1 AC / DC Polarity Measurement (on 2
(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.
