the job.  For example, if the measurement range was .080” (2.03mm) to .250” 
(6.35mm), the user would perform a one point calibration on a known thickness 
sample close to .250” (6.35mm), followed by a two point calibration close to .080” 
(2.03mm).  When a two point calibration is performed, the CMX calculates the zero 
and the velocity.  The following steps outline this procedure: 

 

 

1)  Physically measure an exact sample of the material or a location directly on 

the material to be measured using a set of calipers or a digital micrometer. 

2)  Apply a drop of couplant on the transducer and place the transducer in 

steady contact with the sample or actual test material.  Be sure that the 

reading is stable and the repeatability indicator, in the top left corner of the 

display, is fully lit and stable. Press the MENU key once to activate the 

menu items tab.  Press the MENU key multiple times to tab right and the 

ESC key multiple times to tab left until the CAL menu is highlighted and 

displaying the submenu items. 

3)  Use the UP and DOWN arrow keys to scroll through the sub menu items 

until MATL 2PT is highlighted.
