Division 20 CalibrationF1F2

154 The calibration function shall allow:

• to automatically pair the motion sensor with the VU,

• to digitally adapt the constant of the recording equipment (k) to the characteristic coefficient of the vehicle (w) (vehicles with two or more axle ratios shall be fitted with a switch device whereby these various ratios will automatically be brought into line with the ratio for which the equipment has been adapted to the vehicle),

• to adjust (without limitation) the current time,

• to adjust the current odometer value,

• to update motion sensor identification data stored in the data memory,

• to update or confirm other parameters known to the recording equipment: vehicle identification, w, l, tyre size and speed limiting device setting if applicable.

155 Pairing the motion sensor to the VU shall consist, at least, in:

• updating motion sensor installation data held by the motion sensor (as needed),

• copying from the motion sensor to the VU data memory necessary motion sensor identification data.

156 The calibration function shall be able to input necessary data through the calibration/downloading connector in accordance with the calibration protocol defined in Appendix 8. The calibration function may also input necessary data through other connectors.
