Q on Tektronix P6015

This one looks quite good and is searchable:

Go to Tek's website and download it from there.

I don't think that the 6015 has been available for some time. The

Don't think it'll get much clearer than this:

Just limitations of the original...

Thanks. A lot more modern version, 3 times more wordy, and ZERO photos or drawings of the guts - which figure 4-2 in the older manual is one of two.

Just as non-useful as the modern manual that Jeff referred to. I need that photo of the guts.

Thanks! Exactly what i was looking for. It is item #12,the spring (not summer this late in the year) capacitor that i am most interested in.

Item 12, the "leaf" is actually part of the compensating capacitor. Attached to the low voltage end of R100, it supports a floating ring around the HV end of the resistor, making a fixed capacitor in parallel with R100.

It looks like the bulk of the capacitance is between the suspended ring, and the hot end of the resistor. there's an evident attempt made to minimize distributed capacitance, and keep it as lumped as possible.

If it's going to arc, or corona, that's where it'll happen. I bet they had fun developing that bit.

Check; note rings used on the HV end.

Thanks; all are superior to what is in my copy. The color one is absolutely the best of all.

What I said.

What I don't understand is: you said you have a P6015 yourself, which has lost its dielectric fluid. Why not take just it apart and look and measure? You've nothing to lose. It won't be any worse when you put it back together.

Much better than any photo.

Just be absolutely sure you do not touch the resistor. It will contaminate the surface and kill the accuracy.

See the manual.
