■ 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.

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).
