ADE7753 power up voltage measurement glitch

Question asked by stoyanoff on May 16, 2018

Greetings! I`m using ADE7753 to measure DC voltage. I`m using ACPL 7900 linear optocoupler to isolate ADE7753 from the power line. The problem is on power up the voltage value jumps to 1000V and after few seconds it drops to the correct level(600V). Can you tell me how to deal with this glitch?

Thanks!
