    Operating instructions The STABILA OLS 26 level can be used for many types of measurement on the building site. It can be used for the optical transfer of heights as well as measuring distances and angles. We have endeavoured to explain the unit‘s handling and functioning in as clear and comprehensible manner as possible.

    Levelling the instrument: The OLS 26 is aligned by turning the adjusting screws (1). The bubble of the circular vial (7) must be precisely in the centre. If the bubble in the vial moves outside the central ring when the OLS 26 is rotated through 180°, the circular vial must be adjusted.

    Working with the level Measuring heights 1. Place the level as close as possible to the mid-point between Example: 2 measuring points and level the 2,218 m instrument. 2. Align the level with measuring point A and read off the figure A1. 3.

    Example: 80° Checking the calibration The OLS 26 level is designed for use on construction sites and was perfectly adjusted when it left our factory. As with any precision instrument, however, its calibration must be regularly checked. The unit should be checked before starting any new tasks, particularly when the unit has been exposed to strong vibrations.

    4. Set up the instrument and level it in front of the levelling rod A (distance approximately 1m) Example: 5. Align the instrument with measuring 2,007 m point A and read off the figure A2 on the measuring point. 6. Align the instrument with measuring point B and read off the figure B2 on the measuring point.
