For most setups, the use of one triggerscope so the current method for detecting and setting the voltages through the DAC by parsing TS_DAC from device properties works well. However, in the case of the Mantis where we have the triggerscope device named as TS1_DAC instead of TS_DAC our current string parsing fails.

Check the following:
main_widget.py and Calibration.py will need to have some edits to recognize the triggerscope name.
