Question

Why are LabPro Motion Detector distances in Logger Pro sometimes offset by 1 meter?

Answer

(applies only to Logger Pro 2, not Logger Pro 3)

When you plug an AutoID Dual Range Force Sensor into CH 1 and a Motion Detector into DIG/SONIC 2 of the LabPro, Logger Pro automatically loads an experiment file from the "ExperimentsVSAutoID" folder named "dfs10md-2.mbl". This file is mistakenly calibrated for the Motion Detector distances to be offset by 1 meter.
The easiest way to fix this is to copy a similar experiment file named "ExperimentsProbes & SensorsMotion DetectorMot&DFS.MBL" to replace "ExperimentsVSAutoIDdfs10md-2.mbl".
