Re: VOM Advice? Simpson 260
|
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.
