2. AC Voltage Measurement

Measurement range: 0-600V.

Accuracy: 2% rdg+5dgt.

Resolution:1V.

Test frequency: 50/60Hz.

3. Phase Sequence Test

Phase-phase voltage range tested: 100V-450V.

Frequency tested: 40-60Hz.

①The phase sequence function allows you to test the phase sequence of 3-phase AC power supply (100V- 450V/40-60Hz). When you have connected the phase sequence probes with the test wires by input terminals you can judge the positive phase and reverse phase of phase AC according to LED indicator and beep, and phase missing indicated by LED.

②Test State

Phase Sequence Test Indication	Open Phase Test Indication	Beep
Positive phase (CW indicator is on)	L1, L2 and L3 indicators are on.	Long beep
Reverse phase (CCW indicator is on)	L1, L2 and L3 indicators are on	No beep
Missing phase (CCW indicator is on)	Any of L1, L2 and L3 is not on	No beep

Note: When the measurement probes have been connected, the phase sequence measurement function shall indicate the positive phases and reverse phases of a 3-phase AC, and the LED indicator will indicate the phase missing. Be sure to measure with 3 triple-color test wires with 3 round crocodile clamps

4. Phase Sequence test result is indicated by LED No and display in LCD
