Temperature compensation
The internal temperature compensation reaches the optimum operating point after 3
minutes of operation. Temperature compensation is adjusted at the factory to standard
mounting conditions with an aluminum mounting bracket and mounting nuts.
Temperature compensation is automatically adjusted to the individual installation situa‐
tion under the following conditions.
Conditions of automatic adjustment of temperature compensation
•
The device is in a cold state.
•
Digital output: The digital output is deactivated for approx. 30 minutes.
•
Analog output: The analog output delivers a constant value of 11 mA ... 13 mA or
4.4 V ... 5.6 V for approx. 30 minutes.
If the measured value changes in the 30 minutes, the adjustment is canceled. The
default parameters or the last adjusted parameters are retained. Automatic adjustment
is suitable for installation situations that deviate greatly from standard installation
conditions or where high measurement accuracy is required. One example is thermally
insulated mounting.
