weight. If you attempt to accumulate the next weight before allowing the scale(s) to return
to zero, the error message “Ac
Ac Ac Ac.Err Err Err Err” will be displayed.
The accumulated total weight can be viewed only on the scale you are accumulating from.
After the PRINT/ACCUMULATE button is first pushed; the display will show “Ac. X” as the
system will accumulate the next reading and send it to print. (X will show the number of
accumulations this session) Once a successful accumulation has occurred, pressing the
LOCAL/TOTAL button will cycle the display to show number of accumulations, current local
weight, current total weight on all scales, and the accumulated total. When the local
weight, current total weight, or accumulated total is displayed, the total icon will be lit up,
flashing, or off. (as shown in the display description).
LOCAL / TOTAL
The local weight is the weight on that scale only. The total weight is the weight on all of the
scales in your system. Pressing the LOCAL / TOTAL button toggles between local weight
and total weight. The indicator bars (as shown in the display description) will show whether
the scale is displaying the local or total weight.
Note: If the system is not setup correctly, the “error” icon and message “t0t
t0t t0t t0t” will be
displayed when trying to view the total weight. See section titled “Totalizing Setup”.
ZERO
Sets the weighing system to read zero pounds or kilograms. If pressed while a pad holds
weight, that weight becomes the zero condition for the pad. This can be useful to cancel
the weight of any weighing fixtures, such as tail cones or wheel chocks. When the weight
is removed, a negative weight displays until the system is re-zeroed. This switch is used
any time the scale shows a non-zero value with no weight on the pads.
Note: This system contains a feature called Auto Zero Tracking (AZT), which corrects for
slight zero changes during normal operation. An example of a zero change could be a
buildup of dirt on the pads.
Another function of the zero key is to clear the accumulated total. Press and hold the
ZERO key until the display reads “CLr
CLr CLr CLr.t tt t“ and release the ZERO key. This will reset the
accumulated total and the accumulation number. All other scales you have connected will
also be zeroed through the interconnect cables. This allows you to zero your entire system
with one key press.
