The Setup menu contains the following sub-menus:
Auto-Off [.
A-OFF.]:
Auto Off settings:
On Off
Setting [On] will automatically turn the scale off after no
activity is detected for 4 minutes.
Span Calibration [
SPAN]: Uses two weight values: Zero and a value at or near the full
capacity of the scale. Span calibration should be performed
if the scale is repositioned or if the room temperature
changes significantly.
Linearity Calibration [
Lin]: Uses three weight values: Zero, a mid-range value and full
capacity. Generally this calibration is not required unless
testing shows that the linearity error exceeds the linearity
tolerance in the specification table. Accuracy of the weights
is important to maintain weighing integrity.

See Table 4-1 for the symbols associated with each Unit or Mode.

Additional Menus are available if a serial interface option is installed in the scale. These
menus are explained within the user manual of each option kit.
