P=watts, U=volts, so it's Watts/Volts to get Amps

@ -47,7 +47,7 @@ I used the following procedure to calibrate.
8. Verify the current reading with the calculated value of P (step 6) / U (step 7)) and if needed change the current offset in mA with command `CurrentSet 254.777`.
Example:
`P/U=I`
`Volt/Watt=Ampere (A)`
`Watt/Volt=Ampere (A)`
`A*1000=mA`
`(60.0/235.5)*1000=254.777`
