Hello,

I have doubt in register value calculation:

say i am calculating value of vathr register using below formula:

Ufs=353V(according to my attenuator network for full scale adc voltage )

ifs=7amps(for full scale adc input)

value of n=3 each LSB represents 1kwh

result of vathr using above formula is very large-----------not possible to store in 8 bit register. so how this formula can be used to calculate vathr.

Thanks and Regards

Hi anur

Yes. The VATHR threshold register just allows the user to set the most significant 8 bits. The other 27 least significant bits are 0s. To find the range at which the threshold has to be set, use the equation 44 in the datasheet.
