In recording measured values there are a number of facts, which need

to be considered in order to determine the quality of the measurements.

This means that the person responsible should consider what he expects

from the result of the measurement and how this can best be achieved.

The measurements are affected by:

       - the quality of the calibration template

       - the quality of the optics and the lighting

       

       - the quality of the computer hardware

       - the care taken by the operator

       - the interval between checks of the calibration

       - the correct settings for the video images

When making the measurements please note that some functions have

been programmed which are meant to increase the reliability of the

measurements. For example a query asking for the correct lens can be

activated before saving, or an automatic calibration carried out
