The product calculates the measured
length (see Fig. F) from the travel time
of the ultrasonic signal.
In order to guarantee an exact measure-
ment, the following conditions should be
maintained (see Fig. F):
- Make sure that the product is always
directed at a right angle towards a flat
surfaced wall (see Fig. F).
- The further you are from the wall, the
wider is the area (a) that the product
requires to do the measurement (see
Fig. G).
- The measuring distance range should
not exceed 0.6 m to 16 m.
- E
nsure that there are no objects positio
ned
within the measurement area, which co
uld
reflect the ultrasound prematurely (see Fig.
H). The conical path of the ultrasound
has to be width of 6 m at a length of
16 m (see Fig. F).
- 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.
- The battery must not be empty. An empty
battery is shown in the display
2
by
the battery symbol
.
- If a definitive measurement is not possible,
the display shows the “Err“ information.
The measurement must then be repeated.
