12 Configuration
Linearization
Linearization is dependent upon the probe that is connected (measuring probe).
The predefined linearizations can be supplemented with
customer-specific linearization .

SPECIFIC LINEARIZATION
Measuring value offset, measuring value factor
The value for the measuring value offset ensures a parallel shift of all measured values; the
value for the measuring value factor influences the slope of the values displayed.
Filter time const.
The filter time constant is used to adjust the digital input filter (2nd order filter). If the input signal
changes suddenly, approx. 26 % of the change is acquired following a period that corresponds
to the filter time constant (2× filter time constant: approx. 59 %; 5× filter time constant: approx.
96 %). A large filter time constant means: high attenuation of interference signals, slow reaction
of the actual value display, low limit frequency (low-pass filter).
Scaling start, scaling end
The maximum measuring range limits are displayed here, depending on the probe selected
and the linearization. These limits only affect the recording. If, for example, the scaling end for
a Pt100 is reduced from 850 °C to 400 °C, the recording only displays values up to 400 °C.
