XZ-1D Phase Sequence Table

1. Directly powered by the tested power source, without the need for batteries.
2. Equipped with phase loss indication function: The three red light-emitting diodes A, B, and C on the panel respectively indicate the corresponding three-phase incoming power. When the measured source is out of phase, the corresponding light-emitting tube does not light up.
3. Using sound and light as phase sequence indication: When the three-phase phase sequence of the measured source is correct, the green light corresponding to the positive phase sequence will light up; When the three-phase phase sequence of the tested source is incorrect, the corresponding indicator light will light up and the buzzer will sound an alarm.
