SPEEDBUTTON BAR – Screen Display
See Figure 1 in the Analysis Screens section. The area marked A is the Speedbutton Bar.
The buttons on this bar give quick access to various application modes and features.
Show All Data Points, Last 64 Data Points
, Toggles the “show all data points” mode and the ‘show last 64 data points” mode.
In the ‘last 64 data points” mode, the Graph Display Area (see Figure 1) is updated immediately
as the SV scanner/verifier processes each bar code. In the “show all data points” mode, bar code
processing can continue, but the ScanVision display is not updated until the user toggles back to
the “show last 64 data points” mode.
The Grade Bar (Color Bar) is dimmed when
display updates are suspended.
Zoom In
Toggles the Zoom-In mode. First, it switches from normal mode (displays results for the
last 64 bar codes), to ‘All’ mode (displays all the data points from the session). To zoom-in, hold
down the left mouse button and drag the mouse-pointer to a desired data point in the Graph
Display Area; Hold down the Ctrl-key when the left mouse button is released (then release the
Ctrl-key.) The plots are stretched to show only half of the data on each side of the mouse pointer.
To zoom further into the data, repeat this process.
Erase Current Session Data
Erases all of the data in the current session . Also, the data in the
corresponding hard disk files is deleted.
Reflectance Profile
Scan and Display a new Reflectance Profile . (See Figure 3 in the Analysis Screen Section)
Transmit SV Commands
This button invokes a special screen where up to fourteen individual commands may be
composed and transmitted in any order. Proper use requires knowledge of the SV download
language. See the SV Download language technical manual for details. This function is intended
for advanced setup involving special functions not normally accessed by ScanVision. These can
include special transmission formats, special commands in a custom SV firmware version or
diagnostic functions used by PTX technical service personnel.
