Hi Chuck
I am quite amused by the 40KV probe as rule one is that you do not hand hold such an item when applied to power.
Best of luck
George

Hi George,
Yes, you are right... but then, my keithley 1600A is also
1000M input impedance...
I just tried the keithley on the focus grid, and it did
*not* load it down noticeably.? Clearly, I must have tried
some other scheme the last time I measured it.
I am not sure how I can leave this huge probe connected
given that it isn't amenable to a gripper clip.? A skyhook,
I guess...

The Fluke 40KV probe is 1,000M input, The only other quick solution is an electrostatic meter, but I doubt it would have the resolution that you require.

? That is where I went first, but when my 100M Keithley probe
is applied to the focus grid, it pulls the scope out of focus.
It is a problem when the measurement equipment adversely
affects the measured circuit.
