it is actually the Southwire "10041N autoranging multimeter." I use it mostly for DC mA but occasionally I use it for checking continuity and less often for checking AC voltages.
It looks better. Also seems to have more user friendly features. Accuracy of AC voltage measurements??? It didn’t say it is a True RMS meter.
As for using the meter to check/set DC ma bias it is probably fine. Use the mA rotary switch setting. It should give a more accurate reading than using the 10 A setting.

I am about sure the manual says 270 to 300;
Manual says 275 to 300 ma. My understanding that is too high.
My Son bought a V12 a few years ago at, I believe an Estate sale. He said he was having problems setting the bias. He brought it over for me to look at. I tested the KT88 power tubes in the amp. On the "Life Test" all tested good except two tested good marginal.
What didn't test good was the 4 small signal tubes. He bought 2 new 6922 tubes (input / driver tubes) and 2 SV83/EL84 tubes (Current source tubes).
While he was waiting for the new tubes he searched Cary chat forums on the Net. He found a good site that said the Cary manual bias settings were too high. I can't remember where we set the DC ma bias at. What ever it was he hasn't had any problems with the Amp. That is when he uses it...
