The digital level with horizontal circle was made in 1996. It works similarly to the Wild NA 2000, which is considered the world's first digital level. The encoded division used has a Zeiss shape and dimensions, and the procedure for comparing the measurement signal and the reference signal in the digital image extraction process is different. The instrument determines the distance to the staff electronically with centimeter precision. The standard deviation of the height difference is 0.3 mm for 1 km double-run levelling, which makes it a precise level.
The design of the crosshairs in combination with a conventional levelling staff allows us to use the instrument as an analogue level. The precision of the measurement is five times lower in this case.
The level was mainly used for measurements for diploma theses. Due to its incompatibility with Leica's digital levels and the associated measuring equipment and software, it soon became a museum piece. The instrument is in the same condition as when it was originally taken out of service.
