Advanced Features for Greater Speed and Accuracy

Sokkia’s DT2E Electronic Digital Theodolite has advanced mechanical features for greater speed, accuracy, and convenience. Mechanical features include a dual-axis compensator for improved accuracy in angle measurement, and a simplified keyboard with multiple-function keys which provide access to an extensive range of measurement and calculation functions.

User-Definable Softkey Operation— The four “Soft-Function-Keys” simplify operation and enhance work efficiency and the user-definable feature allows you to allocate any function to any key of any page. For example, the functions most frequently used can be allocated to the first display page and functions seldom used can be temporarily deleted. The large dot-matrix LCD displays four lines of 20 characters to provide full information. The control panels are conveniently located on both faces for ease of use.

Ultimate Accuracy Ensured by the Dual-Axis Compensator—Horizontal angle measurement errors caused by instrument tilt cannot be corrected by observational methods. The only way to avoid these errors is to level the instrument perfectly, or to employ an electronic dual-axis compensator. The dual-axis tilt sensor detects deviation of the standing axis in both X and Y directions. Correction values for both horizontal and vertical circle readings are computed and applied automatically. No other current method can achieve greater angle measurement performance.

Convenient Angle Measurement Modes—Selectable angle units are “degree”, “gon” and “mil”. Horizontal angle measurements can be taken in “clockwise” or “counterclockwise” directions. In the “repetition” mode, the averaged horizontal angle of multiple observations is automatically calculated for maximum accuracy. The 0 setting and horizontal angle hold can be performed with a double key touch. Vertical angles can be selected from “Zenith 0”, “Horizontal 0” and “Horizontal 0 +/-”. The slope can be displayed as a percentage by a single key operation.

Total Station Capability with Add-on EDM’s—The DT2E is capable of total station performance when combined with Sokkia’s add-on EDM’s which can be operated via the softkeys of the theodolite. Slope horizontal and vertical distances are calculated and indicated on the theodolite’s displays

Onboard Software for Total Station Functionality Missing Line Measurement (MLM)—A DT2E, in combination with EDM, enables the measurement of horizontal distances, slope distances, height differences, and slopes in percent (%) between two prisms.

Remote Elevation Measurement (REM)—The height of a point inaccessible for prism placement can be easily determined by simply sighting a prism placed above or below the point and then sighting the point itself.

Interface Port and External Power Plug—The interface port permits connection to the SDR33/31 Electronic Field Books for automatic data collection. Sokkia’s variety of external power supply systems can be used via the external power plug. The port and plug are incorporated in the base, allowing the alidade to rotate freely without cable interference.
