  • Page 19: Distance Calibration

    Distance Calibration Before you can use the Rally Computer to measure distance, you will need to perform a calibration. The device includes a special calibration wizard that guides you through this process using simple on-screen instructions. To calibrate the distance: Find a piece of road with an accurately known distance.

  • Page 20: Fuel Calibration

    Fuel Calibration (TC200 only) The TC200’s fuel measurement system is designed to work with a wide range of tank sizes and shapes. Before it can be used, the system must be calibrated to suit your particular vehicle. This is done using a special calibration wizard that guides you through the process using simple on-screen instructions.
  • Page 21 The calibration wizard works by recording a number of set points as you add fuel to the tank. For best results: • Use at least five set points (up to a maximum of ten). • Add about 5 to 10 litres of fuel between each point. Notes: Many vehicles will not give a correct fuel signal unless the ignition is turned on.

  • Page 22: Turning On & Off

    Changing the Display Units The Rally Computer can display distance and fuel information in a number of different measurement units. To change this, select Settings > Units. Note: The device does not need to be re-calibrated when this is changed.

    Troubleshooting If you’re having trouble getting fuel or distance measurements working, read through this section for solutions to some common problems. And if you can’t find an answer here, don’t hesitate to contact Monit directly for help. Troubleshooting...
  • Page 34 The distance measurements are not consistent / The distance increments when my vehicle is stationary. The TC100/200 works by counting the pulses produced by a speed sensor. Noise from other parts of your vehicle’s electrical system can interfere with this signal and cause distance measurement errors.
  • Page 35 The fuel level changes when I turn my engine on and off The output signal from some fuel senders is proportional to the vehicle’s battery voltage. When the engine is running, this voltage is boosted by the charging action of the alternator. The corresponding change in the sender’s output will affect the fuel level shown on the TC200.
  • Page 36 The fuel level measurements are not very accurate The TC200 uses your vehicle’s fuel sender to measure the level of fuel in the tank. If this does not generate a good quality signal, the TC200 will not be able to make accurate measurements. Unfortunately, many factory fuel senders are designed for low cost, not accuracy.

  • Page 37: Error Messages

    Error Messages ‘Error: No pulses detected’ The Rally Computer is not detecting any signal from the speed sensor. Check your connections and the instructions supplied with the speed sensor. ‘Error: Too many pulses’ The Rally Computer is receiving too many pulses from the speed sensor. Reduce the number of pulses by fitting a divider unit.
  • Page 38 ‘Error: Invalid Fuel Signal. Refer to user’s manual.’ Some fuel tank senders produce a voltage that increases as fuel is added, while others produce a voltage that decreases. The TC200 uses the first two set points in the calibration process to detect which type of sender you have. If this error appears the software has detected the wrong type of sender.
  • Page 39 ‘Error: Level must increase between set points.’ The amount of fuel you specified for this set point is less than what you specified for the previous one. Check your calculations. ‘Error: Maximum number of set points reached.’ The TC200 can store a maximum of ten fuel set points. Repeat the calibration using an increased amount of fuel between each set point.
