How to calibrate the Voltage and Current

[MMMMK (Hook)]

unfortunately，I lost the Power Module，and I brought anothe one ，but the Voltage and Current showed was different from real,How to How to calibrate the Voltage and Current

You may adjust the scaling by choosing ‘Other’ in the Power sensor selection.

well，I know where to adjust，but not know about the parameter of voltage multiplier and amps per volt clearly，what does it mean？

[jwalser (Jacob)]

They are just proportional scalars. Increase/decrease the numbers until the readings are correct.

so,I need know the actual current，and then try to change the numbers to match the real current？
