Accuracy Check of the Distance Measurement
The accuracy of the distance measurement can be checked
as follows:
– Select a permanent measuring section with a length
of approx. 3 ft to 33 ft (1 m to 10 m); its length must
be precisely known (e.g. the width of a room or a door
opening). The measuring distance must be indoors; the
target surface for the measurement must be smooth and
reflect well.
– Measure the distance 10 times after another.
The deviation of the individual measurements from the
mean value must not exceed ±1/16" (±1.5mm). Log the
measurements, so that you can compare their accuracy at a
later point of time.
