Select the channel from the drop-down menu of the Channel box.
The Channel description and the Abbreviation that you have parameterized before are
displayed in the parameter box of the channel.
Activate the trigger function of the channel by checking the Trigger active checkbox.
Activate or deactivate the Retrigger Blocking by clicking the appropriate radio button.
Enter in Max Trigger or Min Trigger respectively, the limit values that are to generate a limit
violation with Max or Min as the cause.
Set the value dM (delta of nominal value) for the gradient trigger in the dM/dt rise or dM/dt
drop boxes. The timebase is permanently set to the double of the cycle.
If the current arithmetic mean value exceeds the maximum or minimum limit value, there will
be the corresponding gradient triggering.
Note
To avoid wrong trigger settings, trigger values are checked for plausibility. If the plausibility
checks fail, the value is rejected and a message with the valid input range is displayed.
