4.1 Selecting the Displayed View Mode (cont.)
Note: During the placement of a very sensitive probe on the part surface, excess couplant may cause erroneous results. To eliminate the
effect of excessive couplant, couple the probe firmly to the part, then press
while the probe is properly in contact with the part.
DIFF/RR% (Differential/Rate-of-Reduction) - The currently measured and user-specified nominal thicknesses appear along the top of
•
the display, while the difference between these two values (measured minus nominal values, expressed in percentage and dimensional
terms) appears in the middle of the display.
B-SCAN (B Scan) - Allows the user to continuously evaluate material thickness by graphing 1 point per second. During the evaluation
•
period, the measured thickness value is displayed along with the minimum and maximum observed thickness values. The display has a
hidden 5-second time-out bar, which starts as soon as the probe is uncoupled. Recoupling the probe before the time-out period expires
allows the user to continue with the same evaluation period. Pressing the SEND key stores the minimum thickness value after the
evaluation period is complete, as indicated by the filling of the time-out bar.
Note: The displayed differences can have either positive or negative values (see Section 4.4 on page 41).
