Issues regarding ATM90E26 energy metering IC
« on: May 20, 2019, 09:58:58 am »
I've been facing strange issue regarding ATM90E26 energy metering IC. I have done all the calculations and my schematics are also fine. The IC shows AC current, AC voltage, power and energy. At first the reading shows exact values on a resistive load but after few hours the when the respective registers are read the ac current register shows correct value but the voltage register show wrong value(the load as well as the input voltage is not changed). I checked the voltage and current using a multi meter. The current value matches but the voltage value doesn't match the reading showed by the multimeter. I compared the reading with other energy meters too.

Any Ideas???
