Biasing Anthem Amp 1

Well I think I did this thing right, but would like to hear from other Anthem or tube amp owners. The manual says bias for 0.4 volts and with the help of related threads I chose the volt setting and adjusted until the meter said .40 volts. Is this correct or did I just shorten the life of my new EL34's? Thanks for any input.
0.4 = 0.40 volts all day long. I can't see any problem as long as you are sure of the scale that your meter was set at.
Thanks Miami The meter was set at the volt range DC. Now lets listen to some music.
