6.2 Angle measurement system

6.2.1 Measuring principle

The tool calculates the angle in each case from two circle readings.
For the purpose of distance measurement, pulses transmitted along a visible laser beam at a certain wavelength are
reflected from the object to which the measurement is being taken.
Distances can be determined from the values obtained from these pulses.
Tool inclination is determined with the aid of electronic levels (compensators), circle readings are corrected accordingly
and the height difference is also calculated from the measured slope distance and horizontal distance.
The built-in microprocessor system allows conversion of all distance units between the metric and imperial systems
(feet, yards, inches, etc.) and digital circle graduation allows various angle units to be shown, e.g. 360° sexagesimal
graduation (° ' ") or gon (g) in which the full circle consists of 400g graduations.

6.2.2 Dual-axis compensator 5

A compensator is, in principle, an electronic leveling system that determines exactly the remaining inclination ("off
level") of the axes of the total station after it has been set up.
The dual-axis compensator determines this remaining inclination of the tool with great accuracy in the line and offset
axes.
All calculations are then corrected automatically to ensure that this remaining inclination has no influence on angle
measurements.

6.3 Distance measurement

6.3.1 Distance measurement 6

Distance measurement is by way of a visible laser beam emitted through the center of the objective lens, i.e the laser
distancer is coaxial.
