Faulty Measurement
A length measurement consists of
several individual measurements.
The result is only displayed, if three
individual measurements have re-
sulted in the same measured value.
Otherwise, the measuring proce-
dure is stopped and a broken line
appears on the display.
Possible causes for faulty measurements:
■ The measuring tool was moved during the measuring
procedure,
■ The measuring tool was not aimed at the target surface
in a right angle,
■ The target surface is out of the measuring range,
■ Taking measurements on sound-absorbing surfaces are
not possible. In such cases, place a piece of solid mate-
rial such as cardboard or plywood on the target surface.
■ Obstructions are within the sound field,
■ Severe motion of air (wind) in the measuring range.
