The defined, data display resolution for each input type is listed in the following
table. If the Data Format of the Input Type supports the resolution up to after the
decimal point, the fractional part of the input reading is shifted up to display in
integers:
In Engineering Unit ×10 format, the valid display range is from -200 to 850 in
integers. The Raw/Proportional format provides 65 K resolution based on the
valid range in EU×1 format of the selected Input Type. The same scaling
requirement applies to the Percentage format, which has 10 K resolution.
