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 volt-
age 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.

Sets the number of output word rate (OWR) samples that will be used to allow filters to settle at the beginning
of Conversion and Calibration commands. This is an integer in the range of 0 to 8,388,607 samples.
