A sample from this course

One topic, as StudyPath teaches it.

Parts and setup of a total station

A total station is a surveying instrument that combines an electronic theodolite with an electronic distance meter (EDM). Mastering its parts – the telescope, prism, electronic control unit, and power supply – and the correct setup procedure is essential for accurate measurements, a key skill assessed in the NUC CCMAS, NBTE, and NCCE exams.
