ster numbers, see above and section 18.6 for descriptions.
It is suggested that these values are read regularly to ensure any changes made in the
settings are incorporated in the calculation.
As the nominal input ranges of the M2x2 are 500V and 5A, the Used voltage range and
Used Current range need to be set correctly to obtain the highest resolution normalized
values. These values are set using the QDSP software.
