UNI-T Multifunctional Voltage Tester Automatic Voltage Diagnostic-tool Single Pole Detection Phase Rotation Continuity Test

This handheld voltage tester is portable to use. It can be used for voltage indication, single pole voltage detection, continuity test and phase rotation test.
Features:
The handheld voltage tester, portable to use.
It can be used for voltage indication, single pole voltage detection, continuity test and phase rotation test.
For AC voltage, the value is indicated by LEDs, the + and - LEDs are illuminated and buzzer is audible.
For DC voltage, the value is displayed on the LEDs and the positive LED is illuminated. If the polarity is reversed the buzzer will sound.
The single pole test is intended only as a quick check.
The meter is powered by 1.5V AAA batteries(not included).
Note:
Please hold the test probes by the handles behind the finger guards.
Self test of the meter: connect two test probes L1 and L2, the continuity LED will be lit and an audible tone should be heard.
