Avoiding measuring
errors
In order to avoid measuring errors, please
note the following information:
The measurement is performed by ultra-
sound, which travels from the ultrasonic
sender / receiver
The ultrasound is reflected from the target
area and received by the ultrasonic receiver.
The product calculates the measured
length (Fig. F) from the travel time of the
signal.
In order to guarantee an exact measure-
ment, the following conditions must be
maintained (Fig. F):
- The reference area (A) must be parallel
to the target area (B).
- The distance to be measured must be
between 0.6 m and 16 m long.
- There must be no objects in the conical
path of the ultrasound, which could re-
flect the ultrasound prematurely. The
conical path of the ultrasound has a
width of about 6 m at a length of 16 m.
- The target area must have a smooth
surface, so that the ultrasound can be
well reflected.
- Transparent surfaces, such as glass,
generally reflect the ultrasound.
in a conical manner.
