Please share the calibration procedure steps for VRMS channels
ADE7758 is configured to read 3 channel AC voltage ( 0 to 300V),
Attenuation Network is 499K+499K and 1K to ground
When all three channels fed thru Variable transformer(same voltage on all three channel)
each channel VRMS register is multiplied with 0.00021.
Channel A works till 1V (a minimum display possible is 1V)
Channel B works till 10V(a minimum display possible is 10V)
Channel C works till 5V (a minimum display possible is 5V)
when the voltage is above 11V all channels display equally.
