- Select from the check boxes, the measurements that are to be made.
- Set the measurement optics, which writes to the corresponding quadruple magnets, by pressing the 'Set Measurement Optics' button. The associated quadruple magnets will be made evident in the neighbouring QTableWidget.
- Subsequent measurements with different measurement devices and profile monitor combinations require a new setting of the measurement optics.
- With the settings in place, press 'Start' to perform the measurement.
- Once the measurement is complete, information related to the collected (hdf5) data and the generated plots, can be automatically posted to the selected elog book by pressing the ELog icon in the application toolbar.
  The data files are appended with the first 9 digits of the run number, i.e., with one second sampling, as recorded at the start of the measurement.
- Before quitting the application, restore the quadruples to their initial values, 'Restore Initial Values', if warranted.
