Part Number: EVM430-F6736

Hi all,

i'm working on EVM430F6736 development board. i given the AC supply as 230V to board. But in my energy meter reading, it shows 210V. How to adjust/ get the 230V reading on this board? is any adjustment happen on Vrms scaling factor? I'm facing this also in current measurement. Pease give me a solution for these problem.

Thanks & Regards,

    Have you referred to the calibration section in Section 6.2 in the user's guide? There are instructions on how to perform both gain and phase calibration. For instructions on how to calibrate without using an accurate test source, please check out the following thread.

    Please keep in mind that this design uses the legacy Energy library which has limited support. For new designs, we recommend using the Energy Measurement Design Center (EMDC) and software library instead. Using EMDC makes configuration and calibration much easier. Check out this blog and short intro video.

    Accelerate your metering design with the new Energy Measurement Design Center and software library for MSP430™ MCUs
