Example: If set the ratio to be 100,it means the primary current equals secondary currentx100 

 

3.3.9 PT Setting 

The PT option sets the secondary voltage (PT2 100 to 500V) of the Voltage transformer(PT) that wires to 

the meter.   

1 

 

From  the  Set-up  menu, use 

 

and   

  buttons  to  select  the 

PT  option.  The  screen  will  show  the 

voltage  PT  secondary  voltage  value.  The 

default value is 400V

Secondary PT setting   

Press 

  to  enter  the  PT 

secondary  voltage  selection  routine.  The 

range is from 100 to 500V

Set PT ratios value 

Press 

  to  enter  the  PT  ratio 

screen. 

The range is from 0001 to 9999
