Power Meter Communication issue, registers not reading the correct value.

The Power meters, based on the manufacturing location may have an offset. 

In some meters the registers starts from Zero and some it is taken account from 1. So the published register list varies accordingly. 

For Ex: If Register 2017 is for Frequency of the meters it will read 50 HZ. 
But for the meter with offset the the Register 2016 will read 50HZ. 

So it is good to check if the meter has got an Offset before proceeding with the communication issue.
