ADE7816 ANGLEx

Hi,

 

I'm working with ADE7816, to make an energy metering based application. Currently i'm in calibrating the chip, i follow AN-1152 (Calibrating a Single-Phase Energy Meter Based on the ADE7816). From the figure 2, after i set IxGAIN to match the current with AC ammeter, i have to go to calibrate PCF_x_COEF because i did not meet the accuracy over power factor. The datasheet says that to get pF i have to read ANGLEx register then convert it into cos phi. The ANGE0 register stores the delay between V and I for A or D. My question is, when will i know that this register is contains delay V and I for channel A and D?

 

Thanks.
