When the mirror is inclined strongly the crosslines will be no longer visible in the ill- uminated image field. This means a decrease in the measuring range as the distance of the mirror increases. In the vicinity of the telescope the measuring range is 30 min. , at a distance of 100 ft. 1 min. Up to a measuring distance of 7 ft (2 m), the decrease of the illuminated image field and the movement of the crossline image out of the illuminated image field remain unnoticeable.
