Re: VOM Advice? Simpson 260

Ralph Mowery
 

The Simpson 260 used several kinds of batteries over the years for the ohms function.  Often a D size for the lower ohm scale and a higher voltage one for the highest ohm scale..  Some odd ball ones by todays standards...Some more standard like several AA batteries and a 9 volt 'transistor' battery .  I think they were started around 1940, but know that by 1956 they were being produced in more or less the newer looking versions.

Here is a link to many manuals on them and probably how to calibrate them.

The simpson requires a 30 volt battery that is generally not available, expensive when found. I have 10 3 volt cells in mine, so consider that expense. The voltage and current work fine without it but no ohms. JUST SAYING

A great multimeter designed by Simpson in 1960s. I had a chance to buy two of them for telecom training center's needs in India.
