If you inspect that thread you'll find the OP listed the wrong model in the thread title, corrected the title and provided a link for the full manual for MO-1252.That may of use to you.
I actually found the manual on my own after I got the reply here, but I did inspect the thread, might be of use.
Got the scope for only $60 shipping included, so if it works all well then that was a deal.
Was outbid on a perfectly good Hitachi V-212 by a flimsy sniper-placed dollar at the same price.
I could be wrong, but it looks like in the picture channel B is set to its max vertical sensitivity (at least down in the mv range), hooked to the 5Vp-p cal signal, but showing less than a full div high. Also, unless its just the way the picture was taken, the horizontal seems to be off as well, or at least horribly out of focus (signal focus/intensity, not camera focus).
I'll report again when I actually get the scope and get to play around with it, hasn't been shipped yet and will probably take about a week after it does ship.
I attached a few more pictures with the trace on them though. What's the most likely thing that can go wrong with it?
