6.5.2 Manual milepost Measurement
In the manual milepost mode, no data can be set or entered; only the log speed is displayed without
intermediate error compensation. This mode is used to backup automatic milepost measurement.
If the D-GPS or another speed indicator is available during milepost measurement, the speed ob-
tained by the GPS or the indicator can be used as the real speed, instead of the real speed calcu-
lated based on the distance and time.
Record the log speed displayed in this mode, and also record a reading of the GPS (or another
speed indicator) as the real speed at the same time. Repeat this operation to obtain enough data.
After milepost measurement has been completed, enter these data to improve the milepost meas-
urement ( for data entry, refer to Subsection 6.5.3, "Display / Alteration / Deletion of Milepost Data").
Refer to Subsection 6.5.1 for details on the operation.
