14 Timer Interval Indicator K3HB-P
■ 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.)
Time Unit Settings Input Type Setting
Note: Set to 10 or 11 when there is a large variation in the display.
The largest measurement range is 30 Hz.
F4
Time band
Displays input A ON time (T).
• Recovery time (TR) of 20 ms is required before
starting the next measurement.
