Pickup some SuperTex depletion mode FETs from Mouser then check out
Application Note AN-D11 "+/- 500 volt protection circuit" .

Gives your test equipment and A/D inputs some fault protection.

Several other "High Voltage" circuits:

I'm sure everyone on this list thinks those are low voltage circuits. :-)
