we use the connection to the chassis ground in the Phoenix connector. when I remove that connection. we do not get any measurements.
In the box between the Keithlay and the object we have put a 5 M ohm resistor. Without that we get very poor measurements on low values (pA). I think that resistor is causing problems. before we got the 2635B we used a Keithley 263 and that worked very well without that resistor and the connection to the chassis.
I do not know much about this so I hope I can get some help.
