 Abstract: During the IAGA workshop 2018 at Conrad observatory, 30 nonmagnetic theodolites of the Zeiss THEO series were tested for their mechanical and optical properties. Next to an inspection of the instruments, the horizontal circle error (collimation error) and the vertical circle error were determined with the help of a surveyor’s level. While half of the instruments were fine, the others were in need of adjustment or repair. Typical problems requiring repair are sluggish vertical axes and mechanical problems of the coaxial fine-tuning. Typical adjustment problems are the position of the image in the microscope and collimation and vertical circle errors.
