Memory Floating Point:
Notes: Returned as 15 bit 2s complement with +- 5% over/under range applied.. Therefore, this
must be considered when scaling values to be displayed at the Modbus master. The following
equation may be used to determine a value for display.
Display Value = MODBUS Value [ (Span Value -Zero Value) 1.1]
32767
+ {Zero Value - [(Span Value - Zero Value) .05]}
