Hello,

According to the EnergyTrace for MSP432 wiki page, the accuracy can range from +/-2% to +/-5%. I'd assume something similar for MSP430. You can read more information about EnergyTrace from the following resources:

Getting Started With EEMBC® ULPBench™ on MSP-EXP430FR5969

Code Composer Studio v7.x for MSP430 User's Guide (Section 3.4 has some excellent FAQs including discussions about influencing factors for the energy measurement accuracy)

Regards,

James
