Snap On MT 3000 Counsellor II Oscilloscope Digital analyzer with Snap On cart and MT 3010 Printer Unsure of working order. It powers up and lights up and the printer turns on. I was told it worked properly last time it was used about 5 years ago. I haven't tried to use it. It comes with user manuals and all the diagnostic hook ups and leads. It also has the 4 gas for emissions. I got this in a package deal with some other things and don't have any use for it. Call 1 Five 1 Three 7O3 s even 392 between 9:00 am and 8:00 pm.
