    Method A

    The bias will trip and should stabilize at some low value like 10 kV but at the current limit 0.260 mA. Under these conditions there is a plasma being formed somewhere, and you are conditioning provided the HV is slowly creeping up, e.g. 1kV/10 minutes. Watch the voltage increase, and if it does not continue to improve, then you are no longer conditioning. In this steady-state current limited mode, once you get to xx kV, the bias will hold 30 kV. The ion gauge is affected by this plasma.
