I am currently in possession of a Keithley 487 - and an FC65-P ion chamber from IBA Dosimetry. The chamber needs to be biased to 500V to function, however the only connection out of the chamber itself the attached triax cable. What sort of connections/adapters would I need to simultaneously read current from this chamber and supply it with a 500V bias?
I recently found this image (below) of the connections required to do this on your 6517 electrometer, would the connections I need to make be the same?
Thank you for your time.

In the triax connector, the current meter HI is the center pin; the current meter LO is inner shield....which will be at DC voltage supply potential.
NOTE: the interlock is shown as bypassed/defeated. This is unsafe.
