Cyclic Voltammetry

The scan always starts at the start bias and then moves to the first and then the second vertex. It does not matter whether the first or second vertex is larger or smaller, and the scan rate is always specified as positive. The number of cycles is a multiple of 0.5.

This CV job can be carried out potentiostatically or galvanostatically. If the potentiostat was previously switched on galvanostatically, then the CV is also executed galvanostatically and the voltage parameters become currents and the current parameters become voltages.

The upper and lower turn values can be set so that the scan direction is not changed at the vertices, but earlier, when a current has been exceeded.

Steady State Staircase

This primitive can be used to output slower steps, whereby each step has a termination criterion based on a change tolerance. For example, voltage steps can be terminated if the current change falls below a certain value.

Each step runs for at least the specified step time, but can terminate early when the stability criterion is met. The stability criterion is evaluated only after the hold time has elapsed.
