  • Page 25: Linearization

    Functions Linearization The input values of the input can be linearized via a table. This feature can be used e.g. to realize linearizations to specification for non-linear curves. The “ Lin” table is always used when S. L in = 1: “Linearization to specification” is set in INPm. The input signals are filled in in units of the physical quantity (scaling result).

  • Page 26: Filter

    Functions Filter A 1st order mathematical filter with adjustable time constant and bandwidth is built in. Output Input The filter bandwidth b. F 1 is the adjustable tolerance around the measured value within which the filter is active. Measurement value changes in excess of the adjusted bandwidth are not filtered. Substitue value for inputs If a substitute value for an input is activated, this value is used for further calculation with a sensor fault, independent of the selected input function.

  • Page 27: Set Zero

    Functions Set zero The function is enabled during configuration (Func r Func. 1 =1. Due to its effect, the display is reset to zero, when e.g. small rest quantities are still on the scale and cannot be re - moved immediately. To prevent excessive use of the zero setting function, the zero offset (page 30) can be provided with an alarm.
