Technical characteristics Absolute coding angle measurement: Advanced absolute code angle measurement technology is adopted to greatly improve the stability of the angle measurement, and the total station does not need to be initialized. If the power failure mode is turned off during the measurement process, the original information will be retained after restarting the instrument. No troubles. Biaxial liquid photoelectric electronic compensation: Adopting international advanced two-axis compensation technology, the instrument can automatically eliminate errors and perform automatic compensation, and the precision and automation level are greatly improved. The graphical electronic bubble and XY biaxial compensation error display make the operation clear. Guide light The guiding light device adopts advanced technology of emitting two different colors of red and yellow indicating light from the same light pipe, which makes it easy for the construction personnel to determine the aiming direction, and the construction does not have a blind spot, which greatly improves the efficiency of the lofting (than the general total station) The lofting efficiency is increased by 20%.) The red and yellow light guides (200m range) are tailor-made for the lofting customers, making it easy to work in dimly lit environments. Long range Full-HF short-distance multiplexing technology improves the signal-to-noise ratio of the system and measures the speed of measurement with very little data. The intelligent measuring ruler dense distribution technology greatly improves the system error correction and self-verification ability, and excellently eliminates abnormal data. New high-performance circuit design, large gain system, and smaller signals we can see. High-resolution, fully digital waveform technology, smaller signals we see and can handle. The fixed reference optical path makes the data more stable, and the longer receiving focal length makes the addition of the optical attenuating component at the receiving end possible, which reduces the optical interference signal and improves the data accuracy.
