Calculation and application of PA-DGS, TFM+FMC-DGS
Exclusive. When working with the diameter of an equivalent planar hole the use of TFM+FMC ensures the accuracy of determining the diameter of the diameter of an equivalent planar hole is ±0,2 mm at depths up to 100 mm. When working with the PA-DGS, even outside the focus area, the error in determining of the diameter of an equivalent planar hole is ± 0.4 mm at depths up to 300 mm.
