Hello all,

I have on the way a Fluke 80K-6 HV probe.  It is only rated to CAT I and from 
the text below it may not be suitable for measuring the B voltage of a linear 
amp esp. one with a large filter cap.  Should I be using something rated CAT 
III?

The 80K-6 is a high voltage probe designed to extend the voltage measuring 
capability of an AC/DC voltmeter to 6000 volts peak AC or DC Overvoltage 
Category I. This means the probe can only be used to make measurements on 
energy limited circuits within equipment.  Examples include high voltage within 
televisions or photo copy machines.

Thanks
Randy AB9GO
