Single-Point For Span Only (Last Zero) Calibration - Cardinal 190 Installation, Technical And Operation Manual

Single-Point for Span Only (Last Zero) Calibration

This calibration method requires one test weight and establishes a new conversion factor
(span) without affecting the zero calibration value stored during the last calibration. This
minimizes placing and removing test weights and is especially useful when checking high-
capacity scales.
This method uses two calibration points, CAL1= and CAL2=. The value of the test weight is
entered when CAL1= is displayed and the ZERO key is pressed when CAL2= is displayed.
CAL1= – First Calibration Weight
The display will show CAL1=. This is the first of two calibration steps. This weight is the
