Start of leg

  1. Go to “Speed Chart” and press [F4] to clear any old speed chart data.
  2. Go to “Time Control”, press [F4] to reset data and enter your start time. ODO should be “0.00”. Press [F1] to save and go back to previous screen (in this case, back to the app main menu)
  3. Go to “Rally” screen and wait for marshal to give you the speed chart.
  4. As soon as marshal gives you the speed chart, from the “Rally” screen, press [X-SQUARE]. This takes you to “Speed Chart”. Enter as many speed sectors as you can (make sure you enter ‘end distance’ and ‘speed’ for a speed sector before moving on to the next), and press [F1] to save and go back to the previous screen (in this case, back to the “Rally” screen)

During the leg

  1. Stay on “Rally” screen. The only editable field in the screen is ODO. Use the number keys to type in any Odo you want, and press [EXE]. The time that appears below the Odo is the ‘target time’ for that Odo. Call out Odo and time to driver.
  2. There are also short cut keys to add 20m, 50m, 100m etc. to the already existing Odo. Play around with the 5th and 6th row of buttons ([X-THETA-T] to [TAN] and [A-B-BY-C] to [RIGHT-ARROW]) to figure out which button adds/subtracts what value.

Adding more speeds during the leg

  1. You might be in a situation where you might not have entered the entire speed chart before the start of leg. If this is the case, whenever you have time, press [X-SQUARE], go to “Speed Chart”, enter speed sectors and press [F1] to come back to “Rally” screen.
  2. Speeds can be entered in kmph, or mm:ss. To enter in kmph, enter any positive value (e.g. 30, 22.77 etc.). To enter in minutes ( or mm:ss), start the entry with a – (minus). For e.g., -8 means 8 minutes, -12.5 means 12 minutes 30 seconds and -15,45 (note the comma) means 15 minutes 45 seconds.
  3. If you want to insert a row in “Speed Chart”, press [F2]. To delete a row, press [F3].

At a Time Control

  1. Press [CARET] and go to the “Time Control” screen.
  2. Enter TC Odo (get the value by either asking the marshal or looking at your trip meter), and check in time (HH, MM, SS on the left hand side of the screen). Restart time will be automatically calculated based on the “TC Restart Time” setting you had made in “Settings”. The Restart HH, MM, SS are also editable – in case the marshal gives you his/her own restart (by noting the time in your time card), edit these fields.
  3. Press [F1] to save and go back to “Rally” screen.
  4. Look at the top line in “Rally” screen and make sure that it shows the last TC’s odo and checkout time.

Using TSDMeter PRO with a non-rally tripmeter

  1. Before the start of rally, go for odo check. Enter the correction factor in the “Odometer” screen.
  2. Before reaching any instruction, press [OPTN] and enter odo value of that instruction in the ‘Roadbook’ field. Instead of pressing [EXE], press [F1] and go back to “Rally” screen.
  3. For your reference, the odo you checked is displayed next to “R”. Corresponding car odo is “C”. You should execute the roadbook instruction (at “R”) when your car reaches odo “C”.
  4. At the instruction, press [OPTN] and change the ‘Car’ field to whatever the car/GPS tripmeter is showing now. You don’t have to change the ‘Roadbook’ field since you had already done that. Press [F1] to save and go back to “Rally”.
  5. Repeat steps 2 to 4 throughout the leg. Call only car odo value and target time to driver.

End of leg

  1. Press [F1] from “Rally” screen to go back to app main menu. Select “Penalties” and press [EXE] to see your penalty in each TC. This feature is available only in TSDMeter BASIC PLUS and TSDMeter PRO.
