Step 4: Press
below the SERNUM selection to input your
block’s serial number. This will activate the VIRTUAL KEY-
BOARD (see the instructions on the display screen and Chapter
3 use the virtual keyboard).
8.5 Auto-V Measurement Mode
The Auto-V measurement mode relies on the two-channel
TopCOAT probe to measure the thickness of
non-coated
material without knowing the material’s sound velocity. This
allows users to record thickness measurements without knowing
the type of material being tested. It also eliminates the need for
calibration standards made of the same material as is being
tested.
8.5.1
Specifying AUTO-V Measurement Mode
Step 1: Connect the TopCOAT probe-cable connector to the
keyed ports on the top of the DMS 2.
Step 2: Power on the instrument by pressing
. The TG
Menu should be open and the TGMODE submenu selected.
Five selections will appear across the bottom of the display
screen.
Step 3: Press
below the selection titled PROBE. You’ll
note a list of probes that can be used with the DMS 2. Continue
pressing until the TopCOAT probe (560TC) is selected.
Step 4: Select the AUTO-V measurement mode by pressing
below the selection titled TGMODE.
(Note that the AUTO-V option will only appear when the 560TC
probe is specified)
NOTE:
Thickness calibration procedures are dictated by
probe type and measurement mode. While in AUTO-V
measurement mode, no calibration is necessary. Instead,
the probe needs only to be zeroed. See Section 8.4.3 to
zero a TopCOAT probe.
NOTE:
During probe zeroing and calibration, use the only
low viscosity couplant to minimize the couplant thickness
between probe and blocks.
