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.
Yes. That's the one I have. How do you set any values if there is nothing on the display while in Sweep mode?
The VacuTrace is a discontinued product, but maybe Jim Hagerman himself can answer your questions better than anyone here. His contact email is on the new website home page:

I'll wait a while and then email him. This product is way unsupported now, and they probably don't want to hear from me, and I would not blame them.
