Phase Rotation

Line 3

Line 2

Line 1

Note :

• Connect three phase of power source as shown above.

• The test is only available while the system frequency is stable.

Step 1. Set the rotary switch to the “W” position.

Step 2. Using the Navigator key to choose the “

“ mode

Step 3. Connect the Red test lead and Black test lead to any of the

line conductor (e.g. Red test lead to the phase Line 1, and Black test

lead phase Line 3).

Note: If the followings occur, the meter will not be able to

determine the line phase:

The screen displays “OLU” and blinking: voltage > 1000V

The screen displays “LoU” and blinking: voltage < 30V

The screen displays “outF” and blinking: frequency > 65Hz or < 45Hz

Step 4. When the BUZZER beeps twice, change one of the test lead

to another line conductor within 3 seconds

The screen will display the result as below:

a) If it displays “ 1 2 3 “, then the phase sequence is forward

sequence

b) If it displays “ 3 2 1 ”, then the phase sequence is reversed

sequence
