I am trying to use our Keithley 6487 to drive one electronic device, but we got some scum/native oxide at the device interface, therefore at first we need to use a high voltage like 250V to break down this scum/native oxide, in order to get electrical signal to the device.((actually it is the electrical field which break down the scum/native oxide). However, once the scum/native oxide is down, the 250V would be all applied over my device; such a high voltage would generate a current high enough (over 100nA) to burn my device. To protect my device, I would like to set the current compliance of 6487 to around 1nA . In 6487 user manual, it did not say what is the smallest current compliance of 6487 when it outputs 250V. could some shine some light on it?

SELECTABLE CURRENT LIMIT: 2.5mA, 250μA, 25μA for 50V and 500V ranges, 25mA additional limit for 10V range. All current limits
are –20%/+35% of nominal.
