how ADE7758 chip knows what ct i am using, assume a ct with burdern resistor of x
it produces 100mv / amp , if i reduce the burdern resistor to half of x then i will get 50mv/amp, how this information is fed to the ad7758 chip. how much mv/ amp i must give. is there any register for this. assume i am connecting 1 amps load i a phase if i read a phase rms current i must get 1 amps how to calibrate this
