Calibration
|
|
===========
|
|
|
|
In order to provide higher measurement accuracy, the PT1000 measurement can be calibrated. The calibration only calibrates the internal :ref:`hw_analog_fe` and not the PT1000 Sensor element itself.
|
|
The Sensor element must be conform with the standard PT1000 norms.
|
|
|
|
Tests have shown, that a calibration is most likely not necessary, because the resolution of the 12 bit analog measurement is far worse than the reistance reading error produced by the :ref:`hw_analog_fe`.
|
|
Calibration might only be necessary if no precission reistors in the frontend hardware are used.
|
|
|
|
Calibration can be performed the following ways:

Command Line Calibration

|
------------------------
|
|
|
|
Use the :ref:`command_line` to invoke the :ref:`shell_command_calibrate` command.
