Timer Interval Indicator K3HB-P 13
Operation
■ Functions (Operating Modes)
F1 to F6
These functions use the internal system clock to measure the time between pulses or the pulse ON time and then display time measurements or
a variety of other calculations.
Function name Function No.
Passing speed f1
Cycle f2
Time difference f3
Time band f4
Measuring length f5
Interval f6
The time (T) between input A pulse and input B pulse
is measured by the internal system clock. If, for
example, the system clock measures 100,000 counts
during time T, then
T = 1 system clock count (0.5
µs) × 100,000
T = 0.05 s
F1 (the passing speed) is calculated internally
using the formula
× 60 (m/min), and the
display, in this example, would be
× 60=
1200 (m/min).

Passing
speed
The reciprocal of the time (T) from input A ON to input
B ON is multiplied by 60 and displayed.
• Recovery time (T
