ADE7880 电能常规累计模式下测量不准确问题

Expert:

Good morning!I used ADE7880 for power testing, and the current, voltage, power and power measurements are accurate in online cycle mode.But in normal mode, 1S reads the register once, the current, voltage and power are all accurate, but the power is not accurate!The read value is one third of the theoretical value, and LCYCMODE is configured as 0x08

What's the reason, please?Are there any other Settings required besides setting LCYCMODE?Thank you for your comments.
