"Standardized Display" Format
The data is represented in bits 14 through 0. An additional bit (bit 15) is available as a sign bit.
In this format, data on the measuring range is standardized and represented in such a way that it
indicates the corresponding value without conversion. In this format one bit has the value of 1 mV or
1 µA.
This format supports extended diagnostics. Values > 8000
listed on page 15.

Significant Measured Values
Because of the display standardization not all of the possible codes are used. In addition,
some codes are used for diagnostic functions. Therefore, the resolution is not 15 bits but
exactly 13.287713 bits.
