For example:
A device with the Code D1 was ordered for the measuring range. On delivery,
the device is pre-set to the basic measuring range
-0.25 … +0.25 mbar
.
This leads to the following configuration options for this measuring range:

4.3.2 Output signal
• Damping affects the analogue output and display.
• In case of square rooting, the DIP switch 2 (symmetry) does not have a
function. The measuring range is permanently set to ‘asymmetric unidirec-
tional’ (0...x).
