[Drake] passband tuning alignment

[Chris]

Hi
 I have a question here.
 I have the later model R4A (11 tubes ). What I have been trying to do
is   probably  stupid to try but no other way. I have the copy of the
service  manual (lost the original) and where it says  on the  procedure
there to get a certain max  agc voltage, this is where I'm not sure my
voltmeter is  doing what it should.
  I have no vtvm for tube  equipment ,instead I have to rely on an old
rat shack multimeter .  Model 22-216,It's at least analog so I can see a
peak.
I have  5 settings  for  voltage.
3,12,60,300,and 1000.
Which one of these is the best for capturing that all elusive max agc
voltage they  have in the  passband alignment section where you are
turning the  4 tiny   little pins in the back of the  passband tuner box
there to get max agc voltage?
It says to tune to 3800 and have  rig at calibrate. Turn  the 4 screws
till  I attain max voltage.
I know that I have to  probably retube this   but I thought least
getting the passband in alignment was a start .
Thanks
Chris
