10 CW-80 Supervisor's Operating Guide
Overview
The various Under and Over arrowheads can be set up like a bar
graph in a sequential lighting pattern to give the CW-80 operator an
indication of how far the weight on the scale is under or over the
ACCEPT range.
The bar graph values which trigger the arrowheads to light are
established in either the Normal Weighing mode as weight units or
in the Setup mode as graduations.
Primary Bar Graph Values — Un 1, Ov 1

The inner arrowheads closest to the ACCEPT display are called the
Primary Arrowheads because their settings determine the ACCEPT
band. As such, they must be set for any Under/Accept/Over
checkweigh operation. These settings for the Primary Arrowheads
are also important because they can be used to trigger digital outputs
for OVER and UNDER conditions (if digital outputs are active).
When the scale weight is just under or just over the ACCEPT range
by 1 display division, the Under or Over arrowhead closest to the
ACCEPT band comes on. Because these are the first Over and
Under arrowheads to light when outside the ACCEPT band, they are
called Un 1 and Ov 1. To allow easy setting of Un 1 and Ov 1 values
without going into the Setup mode, these values can (in most cases)
be set from the Normal Weighing mode using weight values.
However, note in the OPERATE menu graphic below that the
TARGET mode requires Un 1 and Ov 1 to be set in grads while in
Setup mode.
