Note:

To illustrate the difference between DisplayHi, DisplayLo and Scale Hi, Scale Low. Here is a typical example, with input 0-10V, Scale Low=0.00, Scale Hi=100.00, to have better resolution and vision on Bar, set DisplayLo=0.00, DisplayHi=50.00 so that the Bar displays from value 0.00 to 50.00.

The decimal point is defined by Scale Hi and Scale Low, and not by DisplayHi, or DisplayLo.
