Description
Two limits „P1“/„P2“ that can be assigned at will enable
monitoring of production processes. Two tachos to capture
and display rotation speed and velocity as “F1” and “F2”.
“F3” allows recall and display of a programmed calculating
function, for example ratio, difference, stretching/shrinking,
flow, time elapsed with start and stop signal, impulse rate
measurement, period or impulse duration.
