8 How to use
8.1 Measuring conditions
The quality of the measurement depends on the
surfaces to which you are measuring.
Measurement errors
Measuring errors are possible in case of:
Î colourless fluids (e.g. water)
Î clean, translucent glass
Î styrofoam or similar semi-translucent
surfaces
Î strongly reflecting targets that deflect the
laserbeam
Î measurements aimed at moving objects
Causes:
Î Strongly reflecting targets deflect the laser
beam and cause measuring errors.
Î Non-reflecting, dark surfaces increase the
measuring time.
For constantly high-quality
measurements
 Perform control measurements periodically.
 Perform control measurements before and
after important measurements.
