n Function no.
–
Here you set the function no. of your measuring respectively
output function for every channel. These can be found in the
corresponding function no. assignment from the table for the
input respectively output area.
n Measuring cycle
– Here you may set the transducer velocity for every input
channel. Please regard that a higher transducer velocity
causes a lower resolution because of the lower integration
time. The data transfer format remains unchanged. Only the
lower bits (LSBs) are not longer relevant for the analog value.
