Example Length of processing stage 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.

To make calculations using the input pulse to display the passing speed between two points, the distance between the two points and the display unit must be set and the internally measured time multiplied by a certain coefficient. This coefficient is called the prescale value. (For information on settings details, refer to the User's Manual.)
