Managing Threshold Sets
Managing Threshold Sets
The RTU application comes with default threshold sets that you can use to
define test setups. You can also create your own threshold sets, modify and
delete them.
Note: You cannot modify or delete the default threshold sets.
Note: You must be logged in as Admin username to be able to create threshold
sets.
If, after performing tests, you find that the fault detection is too sensitive,
you can do one of the following:

Select a less sensitive threshold set.

Create a threshold set with custom values, and select it in the test
setup. In this case, you will also need to perform a new reference.
To view the threshold sets:
1. From the main menu, select Configuration > Threshold Sets.
2. From tree view, select the threshold set you want to view.
Note: You can only add, modify and delete software packages when the RTU is
used in stand-alone mode.
