I recorded some data on my RPM meter and the defaults were set to read 120V and the respective current was measured at 120V. After the data has been collected, I have an option to go back and adjust the Voltage readings. It should have been collected at 480V. The meter gives an option to adjust a multiplier for both voltage and current on all phases, neutral and ground.
I changed the voltage to X4 to get the proper system voltage, but wouldn't that skew the current reading. I thought the turns ratio of the current is always the reverse of the voltage.... If the voltage is 4:1, the current is 1:4. I just don't know how to reflect that change since its answer for a multiplier and not a ratio. My intuition is to make the current (1/4) or .25% . Thanks for the help.
