Timer Interval Indicator
K3HB-P
Digital Time Interval Meter for Measuring
Passing Speed, Time, or Cycle between Two
Points.
• Measures Wide Range of Pulse Interval Times
Measures, calculates, and displays pulse intervals between two
points. Wide range for pulse interval measurements, from 10 ms to
3,200 s, max.
• Six Measurement Operations, Including Passing Speed, Time,
and Cycle Measurement between Two Points
One Digital Time Interval Meter has six measurement functions, to
support a variety of pulse interval measurement applications. Select
the best function for your application from the following: Passing
speed, cycle, time difference, time band, measuring length, and
interval.
Refer to Common Precautions on page 30.

■ 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.)
