4.2.4 Information on measured errors
When the measured value is transmitted via the 4–20 mA current output, the measuring
device' s relative measured error is made up of the contribution of the digitally determined
measured value and the accuracy of the analog current output. These contributions, which are
listed in the device documentation, apply under reference operating conditions and can
depend on the sensor version ordered.
The measured error of the digitally determined measured value comprises the measured error
of the measuring device and an additional, installation-specific measured error that is
independent of the measuring device.
The device' s measured error is:
