Span calibration procedure
Follow the steps below to perform Span Calibration.
Release the setting value LOCK that disables calibration.
Set the unit for display.
Set the decimal place.
Set the capacity for use as a scale.
If the value set here is exceeded by 9 scale divisions, over scale
display " " will appear.
Set the minimum unit (scale interval) for weighing.
Set the value of the load (balance weight) applied to the load
cell (scale).
Input the acceleration of the region in which calibration is
performed.
Register the initial zero point.
Apply the load (balance weight) to the load cell (scale) and
register the span (gain).
Disable calibration to prevent misoperation.

Span calibration
Setting value LOCK
- Set the balance weight value below the capacity.
- For performing calibration at the rated value in the specifications of the load
cell, set the capacity identical to the rated value of the load cell.
- In the case where load cells are connected in parallel, which can be associated
with a voltage drop by wiring material depending on the connection method, the
input value may differ from the output value in the specifications of the load cell.
In such a case, register the actual input value to perform proper calibration.
- If the region of use changes from the region where calibration was performed,
weight errors may occur due to a difference in gravitational acceleration. Re-
input the gravitational acceleration in the region of use, referring to the
gravitational acceleration correction table.
