(continuous) measurement is in progress, stops the repeat measurement.
The single measurement is performed with the DC bias output, staircase sweep

cleared, and the last single measurement result is stored in the buffer. The
measurement result is displayed on the Single view, Dual view, Graph view, or Roll
view. Also the last single measurement result can be listed and displayed on the
Measure Result dialog box.
