The PAX2A display consists of a large, 6-digit upper display referred to as Line 1 and a smaller 9-digit lower display referred to as Line 2. Line 1
can be configured to show one of several values, including the main input reading, min, max, setpoints or total values. Line 2 can be used to display
several selectable values including; input value, min, max, total, list, setpoint values, and other values. For these values the mnemonics is shown in
the left most digits of Line 2. To the right of Line 1 is a Programmable Units Display. This display consists of 3 programmable digits that are user
defined as mnemonics for Line 1.
