We have integrated MSP430i2041 with another MCU and did calibration with some static load as well.
It is working fine for lower load up to 8Amp with an accuracy of +/- 1%. But when we increase load up to 10A or 12A calculated watt is wrong but the current value is right.
Active watt is showing around 1700watt for 10A and 1500watt for 12A load.
Please guide us which could be possible prroblem.
Looking forward to you for the help on this.
