MVX High Performance Thickness Gauge
9.3 High Speed Scan
The High Speed Scan feature of the MVX increases the overall sample rate from the
standard 4 measurements a second to 32 measurements a second. This feature
enables a user to make scanned passes over an arbitrary length of the test material,
while still maintaining a reasonable representation of thickness over the scanned
area or region. The display will continue to be updated during the scan process, and
when the transducer is removed, the MVX will display the minimum reading found.
The procedure to use the SCAN MODE feature is outlined below:
Using the Scan Mode
1) Press the MENU key once to activate the menu items tab. Press the MENU
key multiple times to tab right and the ESC key multiple times to tab left until
the UTIL menu is highlighted and displaying the submenu items.
2) Use the UP and DOWN arrow keys to scroll through the sub menu items
until SCAN MODE is highlighted.
3) Use the LEFT and RIGHT arrow keys to toggle the SCAN MODE on/off.
4) Press the MEAS key to return to the measurement screen.
9.4 Alarm Mode
The Alarm Mode feature of the MVX provides the user with a method of setting
tolerances, or limits, for a particular application requirement. This feature may be
used for incoming material inspections to verify the material received is within the
manufacturer specifications. There are two limits, or alarm values, that can be setup
in the MVX – ALARM LO LIMIT and ALARM HI LIMIT. However, the user may
choose to activate and utilize only one of the limit values, depending on their specific
application requirements. The procedures to use the ALARM MODE feature are
outlined below:
