Subject: [Heathkit] IO-4235 scope operation question.

Hi, folks,

I'm having trouble getting a trace on my scope. That is to say, I'm just trying to read some p-p voltages while working on an old transceiver. I can get a spot and center it, but I can't get the horizontal sweep to start.
Naturally, all I have is the Assembly Manual for it. Can someone give me some generic help on what settings I've got to use to read this? I've set it up for 10V p-p, but then I attach the probe to the circuit point, the spot goes off-screen like it's clamping. Tried different voltage settings, no luck. The darn sweep won't start. and I've probably got an incorrrect setting somewhere.

​Thanks for the help! 73, Sandy AC1Y​
