We are calibrating a board using the ADE7953 as a power meter.
Initially, with the default values, we observed a low error in the current measurements. For example, with a reference value of 25 mA, the reading was 0.019 A.
After calibrating the current gain register, we successfully obtained the correct reading of 25 mA.
We then proceeded to calibrate the voltage, power factor, and power gain registers, which worked as expected.
However, when adjusting the power offset register, we encountered an issue: the current readings suddenly dropped to half their actual value.
Even after reinitializing the ADE7953 to its default register settings, the readings remained at exactly half the expected value.
Notably, if we adjust the current gain register, we are able to obtain the correct current value.
This phenomenon has occurred with four different boards in similar ways. We have not been able to determine the cause or find a procedure to restore the device to its "factory settings."
We would appreciate any guidance on resolving this issue.
Best regards,
