Welcome to Digatron

This manual covers the operation of your DT-50S instrument. This includes any 52, 53 or 54 instrument. All 50 series instruments
function the same; the only difference is the number of displays.
Both racers and recreational riders can use this instrument. Racers may be interested in recording in time segments, either laps or
sections of the strip or course. Recreational drivers will usually be interested in recording without laps.
This book provides the information you need to quickly set up and use your instrument. It is a great reference guide.
If you are interested in learning more about how your Digatron instrument can help you analyze your engine functions and driving
techniques, please visit our website, www.digatronusa.com, or phone (509) 467-3128.

    Tach Calibration Number (RPM1) The Tach limit requires two separate parameters. The first is the maximum revolutions per minute (RPM) for safe engine operation. The second number, the Tach calibration, allows the instrument to display the correct RPM for your engine. The instrument divides the Tach input signal by the Tach calibration number.
