3-2 Relation between LOAD-CELL Output & Input Sensitivity
If the input accuracy of JWI600 display is higher than 0.13uv/D, it indicates that
every one scale the accuracy changes, the required output voltage of load cell shall
be more than 0.13uv/D. For the platform design, the output voltage of LOAD-CELL
must match with the input accuracy of weight display unit, so the final design must
conform to the following formats. The accuracy should be as large as possible so as
to ensure stable performance of platform.
Using one LOAD-CELL:

N: Quantity of LOAD-CELL
5000: Voltage of LOAD-CELL supplied by
the display unit
5V=5000mV
For lever LOAD-CELL, lever ratio should be taken into consideration.
Using N LOAD-CELLs:

D: Minimum scale
N: Quantity of LOAD-CELL 5000: Voltage of LOAD-CELL supplied by
the display unit
5V=5000mV
For lever LOAD-CELL, lever ratio should be taken into consideration.
Example
The rated load of Load-cell is 750kg and the rated output is 3mV/v.
The requirement of platform scale: maximum weighing capacity is 300kg and
minimum accuracy is 0.05kg.
