FIGURE 4-5—VELOCITY view mode allows measurement of acoustic velocity based on a user inputted (or
manually measured) mechanical thickness.
4.7 Velocity Measurement Mode
(Optional)
This optional view mode displays measured material
velocity (see Section 4.1 to select mode). The mate-
rial velocity calculation depends on the value inputted
for the test material’s nominal thickness. This nominal
thickness value can be manually inputted (Section
3.2.3) or by using the digital micrometer supplied with
all instruments that incorporate the Velocity option.
(Figures 4-5 and 4-6). Note that when operating in
VELOCITY view mode, material velocity values may be
entered for MINIMUM and MAXIMUM ALARMs (Section
3.4)
