四川成都蘇州一光電子經緯儀DT402L帶下對點蘇光DT302L升級

成都位于中國西南地區，是四川省的省會，擁有豐富的自然資源和深厚的文化底蘊。蘇州一光電子經緯儀DT402L是DT302L的升級產品，它在多個方面進行了改進和優化。該儀器采用絕對編碼測角系統，最小讀數可達1″，測角精度為2″。其望遠鏡的物鏡孔徑為45mm，放大倍率為30倍，成像為正像，視場角為1°30′，最短視距為1.0m。儀器還配備了超大屏幕液晶顯示，讀數方便，操作更易上手。此外，它還具備電子式補償器，可自動垂直補償，補償范圍為±3′。其長水準器精度為30″/2mm，圓水準器精度為8′/2mm。儀器使用6V可充鎳-氫電池，工作時間長達15小時。它還配備了激光對點器，可通過面板操作，方便快捷。數據接口為RS-232C，方便與其他設備連接。儀器的尺寸為153×175×328mm，重量為4.0kg，工作溫度范圍為-20℃～+50℃。該儀器可廣泛應用于國家和城市的三、四等三角控制測量，鐵路、公路、橋梁、水利、礦山等工程測量，建筑、大型設備安裝，地籍測量、地形測量等多種工程測量。

English Introduction

Chengdu, the capital of Sichuan Province in Southwest China, is a city rich in natural resources and cultural heritage. The Suzhou Yiguang DT402L electronic theodolite is an upgraded version of the DT302L. It has been improved and optimized in many aspects. The instrument uses an absolute encoding angle measurement system with a minimum reading of 1" and an angle measurement accuracy of 2". The telescope has an objective lens aperture of 45mm, a magnification of 30 times, a positive image, a field of view of 1°30′, and a minimum viewing distance of 1.0m. The instrument is also equipped with a large-screen liquid crystal display, which is easy to read and operate. In addition, it has an electronic compensator that can automatically compensate vertically with a compensation range of ±3′. The precision of the long level vial is 30″/2mm, and the precision of the circular level vial is 8′/2mm. The instrument uses a 6V rechargeable nickel-hydrogen battery with a working time of up to 15 hours. It also has a laser pointer that can be operated through the panel, making it convenient and fast. The data interface is RS-232C, which facilitates connection with other devices. The instrument measures 153×175×328mm in size, weighs 4.0kg, and has a working temperature range of -20℃ to +50℃. The instrument can be widely used in national and urban third and fourth order triangular control surveys, railway, highway, bridge, water conservancy, mining and other engineering surveys, construction, large equipment installation, cadastral surveying, topographic surveying and various other engineering surveys.
