Anybody Using a Hagerman Vacutrace?

Just got one. Looks fine. Manual is really thin on detail. Not sure if this thing is working or not. Powers up but can't see how to adjust parameters like plate and grid voltages. It's like this is a guick-start guide, but no, it's the manual. It says to make adjustments for set-up, but where do they appear? The LED is only operative in Hold mode, but initial settings are done in Sweep. One good thing--it is talking to the scope. Appreciate any help.
