Each IR Track Sensor & IR Beam Emitter pair is monitored and displayed as a single digit in the display. When the alignment is not correct, the digit counts at a rate equal to the alignment problem. If the count is slow, the alignment is close and needs a little adjusting. If the counting is at a fast rate, the alignment is way off and needs immediate attention. Once the alignment is correct, the digit stops counting and you are ready to time a run. |

Vehicle Numbers or Driver Bib Numbers can be entered into the S-Trap prior to the speed run and recalled to the LED Display on the timer console at anytime. Numbers are also printed on the timeslip. |
 |
Pressing the RUN button on the keypad places the S-Trap into run mode. The timer automatically re-checks the IR Track Sensor and IR Beam Emitter alignments before each run and indicates it is ready to time a run. At this point the vehicle entered is displayed on the timer console ready to measure speed. |

 |
The S-Trap can be configured to measure speed in one direction of travel or it can be configured to measure speed in both directions of travel. Using the bi-directional detection mode, the S-Trap can begin measuring the vehicle speed when either beam is blocked. This is the perfect timer for sports requiring speed detection in both directions to validate the speed for the record books. |
 |
When the run is over and a speed has been detected, the vehicle number and speed is displayed on the timer console and printed to the timeslip printer. RaceAmerica offres Data Capture PC Software to connect your PC to the S-Trap and add driver's names. All Speed Results can be stored on the hard drive of the PC withn a Date and Time Stamp. |
