These are initially selected upon SCP-startup. This action will cause an informational message to be logged. The display presents the letters X , Y , XY , XYU , and SK to indicate which wires are currently selected for the respective multi-wire measurement mode and type. Also included are wire names and wire angles relative to horizontal. Finally, the Enter Micro button can be used to call up the WIRE unit and their respective wires for any valid micro to perform the same procedure.
Online help is also available from the panel.
For emittance measurements, data sufficient for a minimum of three WIRE units is required. The maximum number of WIRE units that can be selected with the software for an emittance measurement is currently five. Regardless of the WIRE units selected, all emittance data is calculated with respect to the given micro's first WIRE unit for consistency. Emittance results for the given micro are also always written to this first WIRE unit's database. Error messages are provided to indicate if either an excessive or insufficient number of wires have been selected for the measurement.
