Temperature offset in 0.1 °C
[-50...+50]
Options:
A maximum offset of ±5 °C can be added to the recorded temperature with this parameter.
Line fault compensation
Options:
This parameter is used for setting the line fault compensation.
Selection of options Via cable length and Via cable resistance: For a description, see chapter

Filter
Options:
This parameter is used for setting a filter (floating mean value filter). This can be used to set the output
value as a mean value using three different options.

Inactive: Filter is not active

Low: Mean output value over 4 measurements

Medium: Mean output value over 16 measurements

High: Mean output value over 64 measurements
Important
By use of the filter the output value is "smoothed" via the mean value and is available for further
processing. The filter thus has immediate effects on the thresholds and calculation values. The higher
the degree of the filtering applied, the smoother the result. This means that the changes to the output
values become slower.
Example: An erratic change of the sensor signal with the setting Medium will take 16 seconds until the
output value is through.
