Operation method and precautions of electronic level
The operation method and precautions of the electronic level. The electronic level is also called a digital level. It is composed of a base, a level, a single telescope and a data processing system. detector (CCD). It is a high-tech product of opto-mechanical-electrical integration composed of stripe coding scale and image processing electronic system.
Operation method of electronic level
1) Placement of instruments: The placement of the electronic level is the same as that of the optical level.
2) Leveling: Turn the foot screw to center the air bubble in the circular level.
3) Input the station parameters: input the elevation of the station.
4) Observation: Aim the telescope at the striped leveling rod, and press the measurement key on the instrument.
5) Reading: Read the height difference and elevation directly from the display window. In addition, other data such as distance can be obtained.
Precautions for electronic level
Before using the electronic level, you must pay attention to the following points:
1) Do not aim the lens at the sun. Pointing the instrument directly at the sun will damage the eyes of the observer and damage the internal electronics of the instrument.
element. When the sun is low or the sun shines directly on the objective lens, an umbrella should be used to block it. '
2) The surface of the strip code ruler is kept clean and cannot be scratched. The instrument converts the black and white stripes of the ruler into telecommunication
No, if dust, dirt or scratches stick to the surface of the ruler, the measurement accuracy will be affected or it will not be possible to measure at all.
