Calculation and application of FAR-DAC, DFA-DAC
Exclusive. When working with the diameter of an equivalent planar hole the use of DFA-DAC 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 FAR-DAC, 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.
