■ What Is Prescaling?
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.)
