Functional Description ETAS
Adapting Signals in the Calibration Software
It is possible to adapt or correct the acquired values using mathematical algo-
rithms.
The following methods are available:
• Offset: adding a constant to the measure values
• Factor: multiplying the measure values with a fixed factor
– Conversion to physical variables
Example: conversion of duty cycle to electrical performance
– Compensation of scaling factors of the measure hardware
Example: prescalers in turbocharger measure sensors
Example: measuring in wheel arches with powered axles
• Linearization of measure curves or all measure results
– Correction of measure errors
– Compensation of the non-linearity of sensors
Example: flow sensor, axle speed is not in proportion to the flow rate
The signals measured and their adaptation enable the physical, technical and
derived variables and measure values to be represented in the physical unit
required.
