兩款儀器都配備了高精度的電子補償器，采用液體電容式系統，工作范圍為 ±3′，分辨率達到 1″，能夠有效補償豎軸傾斜，保證讀數準確無誤。此外，它們還帶有激光對中器，對中精度為 ±1.5mm（在 1.5m 處），波長范圍為 630nm~670nm，激光等級為 ClassII。
在望遠鏡方面，兩款儀器的成像均為正像，放大倍率為 30×，有效孔徑為 45mm，分辨率高達 3″，視場角為 1°30′，最短視距為 1.2m。此外，它們的視距常乘數為 100，視距加常數為 0，視距精度為 ≤0.40%L。
DT-02LL 電子經緯儀還具備激光指向功能，其激光軸與視準軸的不共軸誤差控制在 ≤10″，最大距離可達 150m（白天遮陽）。兩款儀器的顯示器均為 LCD 雙行線段式，數據輸入輸出接口為 RS-232C。
機載電池采用可充電鎳氫電池，電壓為直流 4.8V，連續工作時間可達 8 小時。儀器的外形尺寸為 160×150×330mm，重量為 5.2kg，使用環境溫度范圍為 -20℃～+50℃。
English Introduction
The Kolida DT-02CL and DT-02LL electronic theodolites are high-performance measuring instruments widely used in architectural engineering, topographic surveying, road and bridge construction, and other fields. Both models employ an absolute encoding angle measurement method with an accuracy of up to 2 seconds, ensuring high-precision and reliable measurement data. The horizontal and vertical disks use a diametrical reading method, further ensuring a 2-second level of angle measurement accuracy.
Both instruments are equipped with high-precision electronic compensators. The liquid capacitive system has a working range of ±3′ and a resolution of 1″, which can effectively compensate for vertical axis tilt and ensure accurate readings. In addition, they are equipped with a laser centering device with a centering accuracy of ±1.5mm (at 1.5m), a wavelength range of 630nm~670nm, and a laser class of ClassII.
In terms of the telescope, both models have a positive image, a magnification of 30×, an effective aperture of 45mm, a resolution of up to 3″, a field of view of 1°30′, and a minimum viewing distance of 1.2m. In addition, the stadia constant is 100, the stadia additive constant is 0, and the stadia accuracy is ≤0.40%L.
The DT-02LL electronic theodolite also has a laser pointing function, with the non-coaxial error between the laser axis and the line of sight controlled at ≤10″ and a maximum distance of up to 150m (daytime shading). The display of both models is an LCD double-row line segment type, and the data input and output interface is RS-232C.
The onboard battery uses a rechargeable nickel-hydrogen battery, with a voltage of 4.8V DC and a continuous working time of up to 8 hours. The instrument s outer dimensions are 160×150×330mm, the weight is 5.2kg, and the operating temperature range is -20℃～+50℃.
