■ Functions (Operating Modes)
F1 to F6
Functions F1 to F6 provide rpm/circumferential speed and other calculation displays by measuring continuous pulses (frequencies).

F1: Displays rotation (rpm) or circumferential speed for one input.
F2 to F5: Displays the calculation result for two rotation (rpm) speeds.
F6: Displays the passing time calculated from the circumferential speed and the length
of the processing stage for one input.
The basic principle used by the Digital Indicator to calculate the rotation speed (rpm) display is
to count the ON/OFF time (T) for input sensor or other device inputs using the internal system
clock, and then automatically calculate the frequency. This frequency (f) is multiplied by 60 and
displayed as the rotation (rpm) speed.
Input sensor or other input pulse ON/OFF time (T) = Frequency (f) =
• Rotation speed (rpm) = f
× 60
• Circumferential speed = Roll circumference
× Rotation speed (rpm)
• Passing time=
These calculations are automatically made internally and displayed whenever any input pulse
is received.
