Linear Calibration

Linear calibration points provide increased scale accuracy by calibrating the indicator at up to four additional points between the
zero and span calibrations. Access to Setup mode

Alternative Zero Calibrations

During a calibration, the zero value can be replaced with a temporary zero or last zero.
A rezero can be done after calibration. See below for information on alternative zeros.
6.2.1

Last Zero

This takes the last push-button zero in the system (from Weigh mode) and uses it as the new zero reference point, after which
a new span calibration must be performed. This calibration cannot be performed when calibrating a scale for the first time.
A last zero calibration is typically used on truck scales to allow a scale verification to become a calibration without having to
remove the test weights.
6.2.2

Temporary Zero

A temporary zero calibration temporarily zeros the displayed weight of a non-empty scale. After span calibration, the difference
between the temporary zero and the previously calibrated zero value is used as an offset.
A temporary zero calibration is typically used on hopper scales to calibrate the span without losing the original zero calibration.
6.2.3

Rezero

A rezero calibration is needed to remove a calibration offset when hooks or chains are required to suspend the test weights.
Once a span calibration is complete, remove the hooks or chains and the test weights from the scale. With all the weight
removed, a rezero calibration is used to adjust the zero and span calibration values.
