Наличие датчиков линейных перемещений позвол ет определить плоскостность поверхности в дополнительных точках.The value of the values of the difference from zero, the sum of the deviations in each triangle allows to balance the measurement system, which improves the accuracy of determining the slope (deviation of the approximated surface of the plane from the horizontal) and flatness (deviation of each measured point from the approximating plane) of the surface. The presence of linear displacement sensors makes it possible to determine the flatness of the surface at additional points.

In the initial position of the beam, the levels 6 and 7 and sensors 10 are removed. According to index 8, a mark is placed on its surface 5 and beam 1 is turned before the pointer 9 is aligned with this chain. In this position, the measurements are repeated, and so on the entire surface 5. But the I results of the measurements determine the deviations from the | -orizitality of three sides and 1 (reconstructions with a common vertex (support 2).
