Distance Calibration
Calibrate the distance readings of the walking profiler by measuring out 528 ft (160 meters) with a
rolling wheel measuring device. The calibration track should be as straight and level as possible. Once
the test track is prepared, start the calibration procedures through the Calibrate icon in the Collect
window. Select Distance Calibration and follow the steps precisely to complete a successful
calibration.
Set the length of the calibration track. The units can be changed by clicking on the feet (ft) symbol and
choosing the appropriate units. After the length of the track has been entered, select accept.
Once the walking profiler’s front wheel is on the beginning of the track, select
next and push the
device until the front wheel is at the end of the calibration track as indicated in the collection window.
