4.2 Damping
τ
The damping affects the speed with which the output signal reacts to changes in
pressure.
Fixed damping values are assigned to the switch positions
0…7
.
They can be adjusted directly on the instrument.
(Fixed damping values for root functions are assigned to the switch positions 8…F. This
function cannot be selected for the Cerabar S.)
Damping-linear function:
switch positions 0…7
4.3 Locking/unlocking operation
Operation can be locked after commissioning. This protects the measuring point against
unwanted or unauthorised changes to parameters entered.
