Default = 0.7071068 (full scale RMS)
If the application program detects that the meter has possibly been tampered with in such a manner that the
voltage input is no longer working, it may choose to use this internal RMS reference instead of the disabled
voltage input by setting the VFIX bit in the Modes register. This is a two's complement value in the range of
0 ≤ value < 1.0, with the binary point to the right of the MSB. Negative values are not used.
