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.

actual test weight that will be used for calibration

and press ENTER to store. The weight should

be at least one third of the total capacity of the

scale or about equal to the typical loads that will be

weighed, whichever is greater.
