-The Trigger Out on the back panel of the SLICE-QT can be forced to go high to alert an external device to a status change. ​ To program the trigger, from any screen touch I/O > Trigger Out.  You will be presented with the screen shown in <imgref trigger>​. ​ Select those events on the desired channels for which you want the trigger to go high. A logical OR is performed on the set of selected events to determine the state of the output trigger. In the example, the trigger will go high if the minimum temperature set for CH 1 is exceeded, the maximum temperature set for CH 2 is exceeded, the maximum slew rate set for CH 3 is exceeded, or when CH 4 reaches its set point temperature.+The Trigger Out on the back panel of the SLICE-QTC can be forced to go high to alert an external device to a status change. ​ To program the trigger, from any screen touch I/O > Trigger Out.  You will be presented with the screen shown in <imgref trigger>​. ​ Select those events on the desired channels for which you want the trigger to go high.
