Configure Scaling Screen - APM Power

This is used to setup the current transformer ratio to let the APM know what conversion needs to be done.

• i.e., if you have a 100:5 Amp current transformer:
• Primary CT Current Rating is 100 Amps
• Secondary CT Current Rating is 5 Amps

If you are using a potential transformer to lower the voltage input, you can tell the meter what voltage you are applying.

• i.e., if you have 1000 Volts going into the potential transformer:
• Primary PT Voltage rating is 1000 Volts
• Secondary PT Voltage rating is 300 Volts

Select the parameter that you would like to see the percentage of using the Percentage parameter on the Parameters screen.
