Step 3: The FREEZE feature is often beneficial in high
temperature, Minimum-Capture, and other special applica-
tions. Note that the frozen A-scan and thickness reading
may be sent to a printer or stored in a data file.
Step 4: Once
below FREEZE is pressed and ON is
selected, note the at the top of the display. You must
select OFF before the display will be unfrozen.
4.1.3 Using the Minimum-Capture Mode for Enhanced
Measurement
The Minimum-Capture Mode is useful for locating the
thinnest of a series of thickness measurements. In this
mode, thickness is measured 32 times per second rather
than the normal 4 or 8 times per second. The DMS 2
“captures” the minimum thickness measured during the
capture period and displays it, along with its associated A-
scan, when the operator stops taking readings and the Time-
Out period expires. The
Minimum- Capture cycle is the
period of time that the instrument will continuously operate in
the MINCAP Mode.
During a Minimum-Capture cycle, the currently active
thickness and A-scan are displayed along withthe captured
minimum thickness in a smaller “reversed” box (Figure 4-3).
FIGURE 4-3—During the MINCAP Mode, the instrument
measures record thickness readings, at a faster (32 Hz) rate,
then displays the minimum material thickness, and its
A-scan captured during the MINCAP period.
