Welcome to Digatron
This manual covers the operation of your DT-51S instrument.
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.

Page 4: Batteries Not Needed
Batteries Not Needed When your vehicle is running, the DT-50S series instrument gets power from the lighting coil. To use your instrument for an extended time without power from the lighting coil, you can buy a wall adaptor to power your instrument. When your engine is off, the instrument is powered by super caps, which are similar to rechargeable batteries. -
Page 5: Tach Calibration Number (Rpm1)
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. -
Page 6: Recording
Recording The instrument records in sessions called Events (shown by an E), which start each time the instrument begins recording. Within Events, time segments (Laps, L on the display) are created with infrared beacon receivers and transmitters or with a store switch. To end an Event your engine must be turned off, the Exit button must be pressed, or the Tach must go below 200 RPM (this value can be changed on your PC). -
