Calling help for Lamm ML2.1 biasing!

Please help me with a technical question regarding biasing the V2 setting on ML2.1. I lost my manual lately and I just need to clarify one thing before replacing some new 6c33c tubes. My question is when measuring the V2 pot, the point voltage 0.31VDC is representing the plate current, that means the higher the measurement, the hotter the amp will get? Please clarify for me. Thanks very much.

Maybe you wanna re ask. Voltage never represents current.

Well, I am a teach noob but all I needed to know is when I bias on the V2 position. Valves higher than 0.31VDC meant making the tube hotter? I just don't want to fry the amp. I guess many seasoned ML2.1 owners will know the answer.
