NetScan User’s Manual ChartView Software Reference 4-19
Options
Option Settings includes three separate dialog boxes, accessible by tabs, as indicated in
the following screen captures.
Charts
Restricts Scroll Speed to Eliminate Aliasing
It is possible for chart displays to exhibit aliasing when using ChartScan, NetScan, or
MultiScan devices. The aliasing effect can be eliminated from the display by enabling the
“Restrict scroll speed to actual scan rate” feature. This reduces the scroll speed to a
range that results in non-aliased displays.
System
Determines Communication Timeout in Seconds
The system communications timeout determines how long the software will wait before
declaring a detected communications error. If linked to Excel, the system timeout value
(indicated in the above figure) will be overridden by the timeout value in the DDE
Configuration for Excel dialog box (accessed from the Data pull-down menu).
Acquisition
PostView Comment and Auto Re-arm Trigger Options
PostView Comment Enabling this option allows the user to enter a comment in a text box located in the
Setup/Data Destination dialog box. The following screen capture provides an example.
The message is stored in the header file (that is created when an acquisition saves data to
disk.)
The PostView Comment option should only be used for systems having PostView version
3.3 or later. The comment field in the header file is not compatible with the earlier versions
of PostView.
Example of a Data Commentary Entry for PostView
When in PostView (version 3.3 or greater), the data commentary can be read by selecting
Data Commentary from PostView’s Option pull-down menu. The commentary is displayed
in a message box.
