Calibration
Span is also called as weigh span, i.e. indication response to change of standard weight on the load
receptor. The purpose of span calibration is to remedy the difference between the reading and the
standard weight on the load receptor.
There are two different system calibration modes: simulated calibration and material calibration.
Three simulated span calibration methods are available: R-cal, test weights and test chains. For these
methods, it is important to determine the simulated constant which can be calculated using some
formulas. When performing span calibration, the calibration method should be firstly selected, and the
relevant resistor or test weights / chain weights parameters should be entered into the integrator.
The following Span Calibration menu is accessible by selecting “2.2 SPAN CALIBRATION” from the
Calibration Menu as shown in section 5.3.2.
There are two spanning modes available: automatic spanning and manual spanning.
a. Auto Spanning
Pressing STRT soft key enters the following screen:
In case that the belt is interrupted during the calibration procedure, the following screen will be
displayed.
