[Hallicrafters] Measurement of Low Resistance

[Al Parker]

Hi David,
    It sounds like you're a candidaate for an ESR meter (Equivalent Series
Resistance).  They're great for measuring electrolytic filtering
effectiveness.  Garey Barrell put me onto them about 4 yrs ago and showed
me his.  They measure in 100ths of an ohm.  I use mine regularly.  Here's
what I've written abt them b4:
-----------
"I bought the Dick Smith one from
http://www.anatekcorp.com/testequipment/esr.htm
    I use it quite often.  The kit goes together pretty quickly, and if
you
have any problem with it there's a website with lots of FAQ's on what to
do
if it does or doesn't do things, for troubleshooting.  I think I had 1
lead
that I didn't get enuf solder on & it didn't make connection - they
pointed
me right to it.  The ckt board is small, close traces, so I was being
careful not to get any bridges.
        It'll point out poor switch contacts real easy, & other stuff as
pointed out some in
http://monitortest.net/pdf/esrmeter.pdf
like where a short is in a string of paralleled components."
