[Amps] Measuring amp B+

[Randall, Randy]

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
