Notes
A large error may occur in the measurement result unless the following conditions are satisfied during measurement
· The road surface is flat and there is no gradient
· No strong wind is blowing
· Fix the device (iPhone, iPad) to the vehicle
· Good reception of GPS (not possible inside tunnel)
· Do not shift from the measurement gear (lock up the gear and do not kick down)

Other
· The GPS measurement interval is about 1 second according to the specification of the device. Measurement results become rough in vehicles where acceleration is too fast. In that case, please measure with a higher gear.

* For safety, please do not use this application on public road
