[Amps] ME-11A/U R-F wattmeter

[Bruce Lanning]

I recently purchased a broken down ME-11A/U wattmeter and after my repair and repaint, I need to calibrate it. There are 4 four pots for calibration and I have no idea what they do. If anyone has a schematic or can describe to me the calibration procedure, It would be deeply appreciative. I would be willing to pay any copying cost. Please help me out if you can.
