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
