I need an accuracy down just just one KV, thats all. Not too specific.
1kV (note well.. the prefix kilo is abbreviated with lower case k)
that's better than 1% accuracy, which is quite a challenge.
I have access to a whole highschool electronics lab. There's
literally more equipment in it than any member in this forum has.
That's something I kind of doubt.
There's even an 18,000 dollar scope (low voltage though, damn)
Please, tell me what I need, and I can PROBABLY borrow it for a day
or two. I can get scopes, ohmmeters, ammeters, voltometers,
multimeters, frequency probes, resistors, caps, and so on forever.
Seriously, supplies(being borrowed, that is) isnt a problem.
What do I need so I can MEASURE output voltage?
You need to build calibrated E-field probes (search the archives for
details). You set up the probe with your measurement equipment and
put a known voltage on the tesla coil (using a calibrated signal
generator). That gets you the calibration factor for your
measurement system (i.e. if I measure 20 millivolts on my probe, and
there's 1000V on the toroid, then then every volt on the probe is
50kV on the toroid).
You'll need a way to put known voltages on the toroid.
