most digital meters will work. Usually, the important settings for bias are mAmp / mVolt & AC/DC voltage.
You might want a 10's of mV setting. Best to buy such a meter at an electronics company, not a home improvement store.
bought this set it 200m not working still The first one I bought from Lowes did not have the MV but had MA I got confused and took that back was getting no readings! then the second one from Home Depot with the 200 m setting i wasnt getting a proper reading on one tube 45 was the lowest then it jumped around and I almost gave up. I tried calling my buddy that helped me bias last time but no answer when I was at the store. I noticed that the digital read out was only in 2 digits instead of 3 my buddy finally called and I told him the 200 setting had a "A" next to it and the other and a "V" in the section. He looked up the" A "symbol and I think he said it was amps so the other symbol was Volts ahh makes sense now. Hooked it on the bias probes ah yes thats a proper reading lol So I used a 3 month tube and biased them both at 36! Going to play loud a little later and see how it holds up. Im new to this electrical stuff it was stressing me out big time but finally got it down and did it all by my self this time and worked well
I'm just going to say it: If you know so little about electronics, that you don't know how to use a Multimeter, you can get seriously hurt in a Tube Amp poking around.
He helped me twice biasing so I figured I could handle it on my own, played for a while today loud all good! Before I wouldnt consider it but it was pretty easy though.
Come on man he's gotta learn sometime and somewhere, I don't know squat about electronics, I bought a multimeter and asked someone around here how to bias, end of story. I still don't know anything about electronics but I can bias my amp
