PATH: ACTUAL VALUES  METERING  8-BIT COMPARATORS  8-BIT COMPARATOR 1(6)
The two (A and B) 8-bit digitized inputs as well as the resulting sum/difference are available for display. The values are re-
scaled from the original integer numbers using the 8BIT COMP 1 SCALE FACTOR setting.

The values for the six summator outputs are available for display. The values are displayed with the units programmed in
the
SUMMATOR 1(6) UNITS setting.
