up to 1 mm. Install sensors coaxially along the line sounding on
opposite sides of the test object, press lapping to the surface.
Controlling on the display the measured time T to ensure its stability
and the deviation of the time on the
0.1 ... 0.2 μs from the displayed
value, press the function button "SAVE"
, fixing the measured
parameter. For the next measurement remove probes from the
object and similarly make the measurement on the next area. At the
end of the measurements - the average value of the measured
parameter will shown on the display.
8.6.3. Measuring the depth of the crack.
The display shows the schematic of the probes for this mode. For
the measurement install the probes as shown in the picture below
and get first measurement. Then press the function button "SAVE"
, (for fixing the first stage of measurement), move the probe
according the new scheme, and get the second measurement. After
next pressing the function key "SAVE"
, display shows the
calculated value of the crack depth.
According to the procedure adopted in Russia probes installed
according to the following scheme:
