5.1.2 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.

5.2 Alternative Zero Calibrations
During a calibration, the zero value (
wzero
) can be replaced with a temporary zero (
tmpzero
) or last zero (
lstzero
). A
rezero (
rezero
) can be done after calibration. See below for information on these alternative zeros.
5.2.1 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.
5.2.2 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.
5.2.3 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.
