Which of the following function of Electronic Theodolite.
Measure Horizontal angle
Measure Vertical angle
Both A & B
None of Above
Both A & B
An Electronic Theodolite is a precision instrument designed for measuring horizontal and vertical angles in surveying. It replaces the traditional optical readout system with an electronic encoder, which captures angular rotation digitally and displays values on an integrated LCD screen.

The internal mechanism utilizes rotary encodersтАФeither photoelectric or capacitiveтАФto detect the angular position of the horizontal and vertical circles. As the telescope rotates, light rays or electrical signals are modulated, converted into digital counts, and processed by an internal microprocessor to provide high-resolution angular readouts.
Electronic Theodolites offer higher accuracy and reduce human reading errors compared to optical theodolites.
They typically feature an automatic compensation mechanism to correct for small tilt errors.
Data output can often be transmitted to external devices like total stations or data collectors.
Digital readout eliminates parallax and interpolation errors.
Automatic tilt compensation ensures high vertical accuracy.
Requires a reliable battery power source for operation.
More sensitive to extreme temperature and moisture compared to mechanical counterparts.
Civil construction layout and structural alignment.
Topographic surveying and geodetic control.
Most electronic theodolites provide angular resolution ranging from 1" to 10".
Option D is incorrect because the theodolite is inherently a multi-purpose tool for both angular dimensions.
C is correct тАФ Electronic theodolites are integrated instruments capable of measuring both horizontal and vertical angles simultaneously with digital precision.
Always verify the instrument's least count (resolution) when solving problems, as electronic theodolites are generally classified by their angular accuracy (e.g., 2-second or 5-second models).
