Calibration Procedure 

Step 1:  

Access the CAL submenu located in the PART 

menu.

Step 2:  

Adjust the VELOCITY setting until the displayed 

SBA measures 3 inches (or 75 mm if an EN block is 
used)

Step 3:  

Adjust the PROBE DELAY setting until the dis-

played SA measures 1 inch (or 25 mm if an EN block is 
used)

Step 4:  

Recalculate the delay laws by pressing 

 three 

times.
