7. ADJUsTING TARE
7.1 TARE ADJUsTMENT
Tare adjustment is to deduct the weight of a vessel from gross weight to obtain net weight. Tare adjustment is available via
the front button control or by the external contact input.
7.1.1 TARE ADJUsTMENT LIsT
The tare adjustment range depends upon the input strain gauge codes and the excitation voltage as shown in the following
tables.

IMPORTANT
•
The tare adjustment is reset when the excitation voltage, input scaling value A or B (including Teach Calibration) has
been changed.
•
The tare input is stored when the power is turned off.
