4. How to Set the Meter? 


  • AC current CT Value:

     CT=Current transformer primary current value/Current transformer secondary current value

     DC current CT Value:

     CT=Shunt primary current value/5(Signal input DC 75mV)

     CT=Display value/1(signal input DC 20mA,DC 4-20mA)

  • AC Voltage PT Value:

      PT=Voltage transformer primary voltage value/Voltage transformer secondary voltage value

  • DC Voltage PT Value

      PT=display value/input value


     1)Indicator light:"k":thousand,K means that the practical value is display is 1000 times.


     2)Display character explanation:


  • Character Instruction Parameter and specification

     SET Setting 0000-9999

     CT Current ratio 0001-9999


     PT Voltage ratio 0001-9999
