well 0.47 caps, 1uf caps, and 2.2 uf caps read about 5. at 50khz, new and
old. so im assuming thats how it reads.


all 107 power supplys I have here, all 3 100uf caps are reading near 1 ohm,
some a little over.


my new 100uf reads right at 0. (analog meter).

Im working on infocus power supplys, is an ESR of 1 to 1.5 ohm alright
for 100uf caps at 25volts? they are in the primary circuit of a power
supply.



No, that's too high. Expect to see around 0.3 ohms for a 'standard' cap,
less than that for a low ESR type. However, I doubt that 1 to 1.5 ohms is
bad enough yet to be stopping the supply from working, but replace them
anyway.
