Purpose: The VUPDN class describes a dual voltage-ramp waveform which can be applied by a potentiostat while in the Potentiostat mode.

The voltage is ramped from an initial voltage to an apex voltage and back again to a final voltage. Vupdn objects are normally used for cyclic scans such as pitting tests. The object encapsulates information about the initial, apex, and final voltages, the ramp rates, and the data-acquisition rate.

VUPDN objects use a staircase waveform. Data are sampled at each level on the staircase.

If the Skip button is pressed during the initial phase of the run, the Vupdn signal generator advances to the final phase. If the Skip button is pressed during the final phase, the Cpiv.Run() is prematurely ended.
