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.
Example: F1 Passing Speed
The time (T) between input A pulse and input B pulse
