Inspection of perpendicularity and parallelism on large structures (Fig. 9). Suitable instrument for outdoor
applications.
To conduct high precision measurements of parallelism (Fig 10) (e.g. guide way rails two or more)
The reference instrument (R) will compensate for all changes in the objects orientation while measurements are
made. Using this method the instrument (sensitivities up to 1 µm/m) allows determination of the exact shape of the
guide ways.
Torsion in guide ways and work piece surfaces (Fig 11). The instrument (M) is moved step by step in direction
of X, noting the reading at each step after allowing sufficient time for the instrument to settle. (Attention: Measuring
axes have to be parallel!)
This procedure is also applied when fastening work pieces in order to see possible tensions.
