Note 3 : Value read in 0th address of input register gives the measured value.Also, the 1st address of the input register
specifies the decimal part of the measured current value.
For example ;
Value read in 0th address of input register is 2842, if value read in 1st address from input register as 1, it is 284.2
Value read in 0th address of input register is 2842, if value read in 1st address from input register as 2, it is 28.42
Value read in 0th address of input register is 2842, if value read in 1st address from input register as 3, it is 2.842
