Hi,
I have query about this as I'm on the lookout for a 5digit DMM that can handle up to 1kV (tube amps, solid state and other general electronics). I'm thinking that the BM869 would suit this requirement but reading the mVac threads, I'm in doubt.
The scenario I specifically want is the ability to measure the top of a triode cascode (320Vdc+small Vac) or power output stage (400Vdc+ with a small mVac to large 100Vac waveform).
Short question - can the BM869 do that or not?
Now I could use a HV film cap and measure the AC, but would auto ranging Vdc up to 800Vdc with a 100-200Vac component work to measure the Vdc side with the BM869?
(I have a scope but I'm looking for DMM)
