Step Three:
Setting velocity
Sound velocity plays an important role in measurement. Different material is
of different sound velocity. When the sound velocity is incorrect, it will cause
wrong measured results. There are 3 ways to set the material's sound
velocity, which are:
1. Directly select preset material velocity. Please refer to 8.2.1.2 on page 3.
2. Input the new velocity which is not preset into the menu. Please refer to
8.2.1.3 on page 4.
3. Get the accurate sound velocity of the workpiece which the thickness is
known. Please refer to 8.2.1.4 on page 4.
Step Four:
Measurement
The DC‐5000 is now ready to measure. There are four different
measurement view options, A‐Scan RF+, A‐Scan HALF+, B‐Scan and DIGITS,
each with a specific purpose.
A‐Scan RF+: It shows both the positive and the negative peaks.
A‐Scan HALF +: It shows the positive.
B‐Scan: It displays a time based cross section view of test material.
DIGITS: It is a basic digital thickness gauge look and feel. The color and larger
digits make it much easier for the operator to monitor the thickness
readings.
User can toggle between the different view mode options by pressing .
