Hickok 5900 Function Generator

I just powered up my Hickok 5900 and so far so good, next thing to do is to calibrate this unit and find it a home on my bench.

I have one of those function generators. I would be interested to see the actual calibration and results. My unit only has 2.5 volts peak to peak on the 50 ohm outputs. This does not seem right to me but the book doesn't actually tell the limits of the amplitude adjustment.
