Example: Find the time the photocell will see a ¼" registration mark at 70 Ft/Min
Answer: .25 inches X .0714 Sec/In = .018 Seconds or 18 mili-seconds.
For Speeds Not Given: Ft/Min ÷ 5 = In/Sec 1 ÷ In/Sec = Sec/In
1.000 = 1 second
0.100 = 100 mili-second
0.010 = 10 mili-second
0.001 = 1 mili-second
0.0001 = 100 micro-second
