The legendary electronic second-order theodolite was made in 1986. The instrument has a cutting-edge levelling method with only two tangential foot screws, which ensures a constant height of the instrument's Y-axis. It has a built-in two-axis electronic compensator. The glass supports of the circles have an incremental encoder. When switched on, the instrument always re-defines the zero point of vertical circle by resetting the telescope over the horizon. The four screens display the values of horizontal direction and zenith distance and the tilt of the station axis, and the instrument can also calculate the horizontal distance and height difference if a DM-series distance meter is added.

The instrument was purchased in 1989 and was the first electronic theodolite at the then Faculty of Architecture, Civil Engineering and Geodesy. It was used for precision geodetic net measurements until 2007, most often in combination with the Kern Mekometer ME5000 precision distance meter.

The instrument is in the same condition as when it was originally taken out of service and is still fully functional.
