2CALIBRATION BACKGROUND INFORMATION
Span calibration uses test weights to calibrate the
indicator to a specific set of load cell or load bars.
The known test weight which is used for calibration should
be at least one third of the total capacity of the scale.
Ideally a known test weight about equal in weight to the
load or animal to be weighed is required.
During span calibration process the operator is required to
set desired capacity, resolution of the scale and enter the
amount of the test weight. The indicator will take two
readings, one without the test weight on the platform and
one with.
