Description

Technical field:

[0001] The invention relates to an electronic level gauge, in particular to an electronic level gauge with level indication. Background technique:

[0002] The bar code of the leveling scale in high-precision geodetic leveling requires high processing accuracy. Whether it is spraying process or laser firing, the process error is required to be controlled at the order of tens of μM. Although there are many kinds of processing technology for controlling this method, but there is no reticle in reality. The base surface of the tape is flat, and the reticle is convex. The image of the instrument is clear, and the precision control level in the process is high, which meets the requirements of the first-class geodetic precision measurement standard. However, with the emergence of electronic levels, the processing method of printing patterns on the scales is not suitable for the requirements of the leveling scales used by electronic levels. The leveling scales used ...
