Shear Calbiration

Setup: V=3230 m/s - Range =250 mm - Probe data


( F, Angle 70, Dimension 8*9)

1- Distance calbiration
Determine X- value
Probe delay

2-Angle check

3- Sensitivity calb.
Step 1: adjust probe angle = 70°

Step 2: adjust velocity


Step 3: put the probe on point (E) in which face of probe to the curve and move it front
and back to get the highest peak to know the location of exit point

Step 4: adjust probe delay to make s.p = 100 mm


Step 6: put the probe on angle scale while probe face guided to plastic hole then move it
front and back to get the highest peak on screen then adjust the angle on the device

Step 7: Make device detect small hole ( T) then raise the gain to 80% .
