Calibration Data File and Report

At the end of the calibration process, a dialog box showing the
calibration report will be opened for review. The calibration data file
and a text report are saved in the “LDS-DactronCalib” directory. You
can view the calibration report in text mode at any time. This Calibration
Report is the basis for any calibration certification requirement.

Preview of the Calibration Report

To use the calibration data file, copy it into the \BIN folder where the
LDS-Dactron software application resides.

Important

The calibration software does not copy the
calibration files to the \BIN folder. This must be
done manually by the user.
