Line3

NOTE : 

 

-

   

Connect the three phases of the power source as shown  

     above. 

-   

The test is only possible while the system frequency is  

     stable. 
1. Plug the Black test lead into the COM terminal and the Red  

    test lead into the V-

 

terminal. 

2. Set the rotary switch to the “ RST ” position. 
3. Connect the Red  test lead to the supposed phase 1, and the  
    Black test lead to the supposed phase 3. 

    a. If the voltage < 30V, it display will show “

Lo V

” ; if  voltage  

        > 1000V, then it will show “

OL 

V

”. 

    b. If the frequency is not 50 Hz or 60 Hz, then it will display   

        “

out. F 

”. 

    c. If the voltage and frequency are normal, the display will 

        show “

L1

” for about 3 sec. 

4. If the display shows “

L2

”, the BUZZER will sound twice.  

    Connect the Red test lead to the supposed phase 2 before  

    the “

L2

” has disappeared. 

5. When “

L2

” has disappeared, the display will show the testing 

    result.
