Checkbox -
The user can enable or disable certain functions and properties with the check
box, by clicking on the box. If the checkbox is ticked, the parameter is enabled. In contrast,
if the check box is empty, the parameter is disabled. (The check box represents boolean or
binary type parameters.)
Unit -
This displays the unit of parameter where applicable. Not all parameters have units.
Range/Step -
This applies only to text fields; it displays the range a value can take. The step
value represents the amount by which the value can be incremented/decremented. For
example, if a parameter has a default value of 100 with a range of 1-1000 and a step value
of .01, its value can be changed to 99.99, or 99.98, or 99.9, or 99 or 100.01, or 100.02, or
100.1, or 101, and so on. The value cannot go below 1.00 or above 1000.00, since that would
be out of range. As another example, if the same parameter had a step value of 5, then we
could only change the default value of 100 to 95, or 105, and so on.
Figure 4-6 Main menu view with and without multiple parameter sets
Modified parameter values can be written into the selected parameter set by clicking Set
parameters button on the main menu panel. In case of a device with only one parameter set there
is no parameter set selector combo-box, as it can be seen on the right side of Figure 4-6.
Values are checked for change before the user navigates away from the actual page or another
parameter set is being loaded. By pressing Cancel, the browser will remain on the actual page.
By pressing OK, the browser will ignore the changes made and navigates away to the page
selected.
