Notes
- 1.The instrument shall not require an absence of
obstacles in the field of view of ±7 . When measuring a
long distance or in a narrow space, the ultrasonic pulse
will touch the nearest object in the range of ±7 first.
The value displayed by the LCD is the distance to the
nearest object.
In the figure, the instrument measures the distance
to the ladder, not the distance to the wall.
- 2. Do not aim the laser beam at the eyes.
- 3.During measurement, the rangefinder shall be
perpendicular to the measured surface.
- 4. If the measured surface is rough or its material is
soft, the measurement will be affected.
- 5. If there are other ultrasonic emission sources around
the rangefinder, the measurement will be affected.
- 6. The rangefinder will display "ERROR" under
following conditions:
a. The measured distance is shorter than 55 cm or the
strength of the ultrasonic signal reflected from the
measured surface is insufficient.
b. The sum of the distance exceeds 300.00 m.
c. The area exceeds 225.00 m
d. The volume exceeds 3,375.0 m
