I got an old Fluke 23 (first series I think, doesn't say Series II or anything else) that I've found about 15 years ago in the hole filled with grease, oil, metal sraps and general dust. Initial cleanup took a bit of effort but it still works fine. After all this years I realized I don't even know what accuracy it has, tried to google some data or user manual but the oldest I can find is series II. Has anyone seen anything on the net about this model or maybe remembers basic specs?
