Note.
After plotting the calibration curve, there is no point in changing the units of defects
measurements.
Before plotting the calibration curve, it is necessary to delete all points of previous calibration
curve by pressing
key.
Select the type of measurement in the cursor "Type"
– Pk-Pk. Move to the "Position: " menu
item and by the
,
and
keys, position the central line of the cursor on the peak of
signal from the min defect. Move to the “Width:” menu item and increase the cursor width to
such an extent that only one friendly signal could get there, i.e. the signal from the defect (see
Figure 31). Having placed the cursor on a defect, press the
key
– add the calibration
curve point.
With the help of
,
keys, move to the "CURVE POINTS"
– 1) and by
,
and
keys, set the depth of the first defect of the calibration curve, i.e.0.1 mm (see Fig. 31).
Then it is essential to perform similar operations for all other defects by setting corresponding
depth.
