87V schematics!

Also mirrored 87V/AN full PDF. Thanks!

Thanks Chris.

In a time of crappy unboxing youtube videos, 99.9% of the people would look at the CD and think it was a digital copy of the user manual, legalese, etc and just chuck it aside.

So thanking for actually looking and posting the information.  It will make fixing 87V in the future easier for us.

The 87V service manual did not come from the CD packed with new units. It was on a burned CD I picked up somewhere.

Fluke explains how it works on page 11+ (actual PDF page 19+)

The MOVs are only there to prevent arcing across the switch.
