Simpson 260-1 VOM/Multimeter: History, Repair, Overview, Demonstration, Theory
**** See addendum video:
https://youtu.be/sPCeqSZ7vtQ?si=vYtnpdT9Pj8OySMX
In this video, I describe a piece of classic electrical test equipment, the original version of the venerable Simpson 260 VOM (multimeter) which dates from the early 1900's. Then I demonstrate it, give an overview of the original users manual and schematic, then describe the circuit theory using my CAD re-drawn schematic.
I also present my efforts to replicate some original battery labels, and others who have needed to replace the original cells & batteries on these, using modern equivalents, might wish to apply these so their meters look more period-authentic internally.
The new schematic and label PDF files may be downloaded here:
