THEORY OF OPERATION
The Model 3850 Timer AC4 is a completely
self contained race timing system made with the
latest technology CMOS circuit components
to provide a highly accurate autocross timing
solution. The system contains an internal quartz
crystal clock to maintain time accuracy and display
of race results to one thousandth of a second.
The AC4 can operate with a single sensor
(lap timer) or with dual location Start/Finish
sensors. The system can receive data from either
wireless track sensors (T-Links), hard-wired track
sensors or manually from the console keypad.
Desired settings are selected in a configuration
menu and retained until changed at a later time.
