Dakota Ultrasonics UMX-2 - Manual (Page 12)

UMX-2 Underwater Material & Coating Thickness Gauge
8
4 Digit , 8 Segment LCD Display
The 4 digit display illustrated above, is considered the primary measurement display
of the UMX-2. The following outlines the measurement display: The numeric portion
of the display consists of 4 complete digits preceded by a leading "1", and is used to
display numeric values, as well as occasional simple words, to indicate the status of
various settings. When the UMX-2 is displaying thickness measurements, the
display will hold the last value measured, until a new measurement is made.
These eight vertical bars form the Stability Indicator. When the UMX-2 is idle, only
the left-most bar and the underline will be on. When the gauge is making a
measurement, six or seven of the bars should be on. If fewer than five bars are on,
the UMX-2 is having difficulty achieving a stable measurement, and the thickness
value displayed will most likely be erroneous.
3.2 Single Button Operation
The UMX-2 is controlled using a single button to move around the menu structure
and enable/disable its features. There are 3 basic ‘button press’ sequences available
as follows:
Press & Hold:
Primary function – enter into, or exit out of the menu structure.
When the button is pressed and held down for a specific duration of time, the single
level menu structure will begin scrolling through the top level of menu items
continuously. If entering into the menu structure, “Enter” will be displayed, followed
by scrolling through the menu items. If exiting the menu items, “Exit” will be
displayed, followed by advancing to the current storage location (i.e. A 1), or
“MEMOFF” if data storage has been disabled by the user. Once either instance has
occurred, the button can be released.
