Telemetry Sensor Settings
The DX3R PRO allows you to modify the settings for
the Speed, Temp, and Batt sensor.
Tele: Speed
Unit: Select MPH or KM/H display units.
Roll Out: The Roll Out function is the internal calculator
that can convert rpm data to mph or km/h. The DX3R
Pro roll out is in feet. When the Roll Out value is set to
1.0, the default setting, the value displayed on the main
screen and stored in maximum speed is true rpm of the
shaft gear or flywheel that the rpm sensor is hooked
up to. In order to program the unit to display speed in
mph, a conversion factor is needed. Following are two
methods of determining the conversion factor.
Method A
• Mark the clutch bell that the sensor is reading from
with a small reference mark. A marker works well.
• Set the car next to a ruler and at 0 then roll the car
forward by hand, counting each revolution of the
reference mark. At exactly 10 revolutions stop the car.
• Measure the exact distance the car traveled in ten
revolutions and divide this distance by 10, then
divide this number by 12 to get to feet. (e.g., 12.0”
divided by 10 = 1.20”, 1.20” divided by 12 = 0.10).
• Adjust the Roll Out value until 0.10 appears on
the screen. Now all the rpm related functions will
display in mph or km/h.
