Interval Function
The Interval function uses the photogates to record high-accuracy time intervals� With one or two
photogates plugged in, the DataCollector will record the duration that the beam of each photogate
is broken—labeled as t
A
and t
B
—as well as the time elapsed between the breaking of the two photo-
gates� This last value is labeled t
AB
�
This mode is used to emulate the function of a CPO Science Timer and can be used to conduct ex-
periments with photogates or the CPO Science Sound & Waves machine�
