Measurement Modes
|
|
Mode 1
|
Signal monitor, Gate alarms can be active but no measurements are displayed.
|
Mode 2
|
Depth and amplitude of first signal in gate.
|
Mode 3
|
Echo-Echo distance measurements.
|
Mode 4
|
Trigonometric display of beam-path, surface distance (including X-offset) and depth of indication from the inspection surface together with echo amplitude. Curved surface correction canbe applied for convex and concave surfaces. Half-skip can be indicated on screen.
|
Mode 5
|
Gate to Gate distance measurement
|
Mode 6
|
Flank to Flank
|
Mode 7
|
Beam Angle, calculated from beampath, hole radius and hole centre depth.
