CALIBRATION PROCESS OF DIGITAL SYSTEMS
Each single sensor is individually calibrated over the complete measuring range as well as over the
complete temperature range the sensor is going to be used in. These calibration values are stored as
reference points in the EEPROM of the sensor.
Two temperature calibrations are available:
The standard temperature calibration is well suited for sensors that are used in a typical laboratory or a
machine shop environment: temperatures around 20 °C and slow temperature changes.
The HTR (High Temperature Range) calibration is suited for those sensors that are exposed to outdoor
conditions. These sensors are calibrated at various temperatures, which ensures that they function well
across the entire temperature range the sensor can be used in, which is from –40 °C to +85 °C. Thanks
to the extended and more elaborate temperature calibration, the HTR sensors show a substantially lower
temperature coefficient, which is 1/5 of the value of a standard temperature calibration (see technical
specification).
