Product Number: ADE7868
Software Version: -
ADE7868 provides correct VRMS and IRMS values before configuring the integrator.
We are currently using a Rogowski coil to measure current and have gotten accurate VRMS and IRMS values.
AVRMS = 2587576 on VGain = 0x80F9060F, Voltage measured is 254 V
However, when we set DICOEFF as 0xFFF8000 and then CONFIG register as 0x01, we get
AVRMS = 21504 on VGain = 0x80F9060F, Voltage measured is 240 V
This happens every time we activate the integrator, and as per datasheet, integrator should only be available on the Current ADC path, so we would appreciate some insight as to why the integrator is affecting the Voltage readings.
Thanks and regards,
