3. the machining precision of the machined surface of the large-sized bottom plate is difficult to guarantee, a machining knife edge may exist in part of positions, and the arrangement of a flat ruler may have great influence;

4. the bottom plate of the device may not be a complete plane, and if the flat ruler cannot be completely released from the bottom plate of the device, the middle neutral part can be greatly deformed, so that the measurement accuracy is affected.
