8.2.4.4. Options
Clicking the 'Options' button in the Visual Grad-13 main window brings up the window shown
in Figure 16. This button will be greyed out if a scan is running.
Two different options are available, 'Calibration'and 'On Startup'.
The first tickbox, 'Use Calibration Details from:', allows a user to select an alternate
calibration file to apply to the Grad-13 data. This option is primarily for use by the Bartington
Instruments technical team to apply additional calibration values should it be required. The file
is in.txt format, and can be edited using Notepad.
Note: Applying correction coefficients will affect the display of data but not the recorded
values until they are exported to Excel.
The three tickboxes 'Display Reference Graph', 'Display Sensing Graph', and 'Display
Gradient' Graph, can be selected so that the graphs will be displayed when the Visual Grad-
13 application is first started. By default these are unchecked and the user must click on the
display graph buttons.
