UG20DL Measurement Modes Explained
:

underwater ddd Pulse - Echo Mode (PE)
The normal display mode, measures the total thickness from the base of the transducer probe to the material density boundary (typically the back wall). Ideal for pit and flaw detection.



under
Echo - Echo Mode (EE):
Also known as the ThruPaint™ Mode, EE ignores the·coating thickness, displaying the material thickness from the top surface of the material to the material density boundary.



under
Pulse - Echo Coating Mode (PECT):
Displays both the material thickness (PE) and the coating thickness (CT) at the same time.

UG20DL Display Modes Explained




under  

Material Thickness Digits Display:

The standard display on all models, this displays the numerical thickness value in either millimetres (MM)or inches (IN).

   
 


A-Scan Display; Full Wave (RF):

The A-Scan display shows the sine wave created by the reflected sound, or oscillation, from the material being measured. In RF mode the full wave form is displayed.
 
 

 

A-Scan Display; Rectified (+ or -):

Users can select to view either the positive or the negative cycle of the full waveform (RF). This rectified(RECT) display shows the amplitude of the echo versus the transit time.
