Default ESR meter.. Where to buy what to get.

In my opinion, it simply is a question of waiting for the digits to
settle down or to read the analog meter of that old Cap Wizard
quickly and directly.

For general service work, one finds that 3 % accuracy of the full
log scale is of little consequences with today's electrolytes and so
the Cap Wizard wins again by speed alone. :-)


I don't get where this speed thing comes from. I've seen people mention it
before.



That speed thing came from the not so far away past, when some
people starting to say "it has to be digital, we don't want analog meters."
Of course, at that time (end 1970's ?) they had lots of time to mention
that while patiently waiting for the slow update/ADC on their digital
meter displays.


You don't have to wait for anything with the DSE Genie. It reads "
00 ". You stick it across a cap, and before you can switch your eyes from
the cap to the display, it's reading " .80 " or whatever. No speed issue.
No ambiguity. No waiting for lights or needles to settle. No waiting for
digits to settle. Point eight ohms. Period.


That is great!
And how does it read the ESR of a bad cap. during
temperature changes? Can you read it as nice, easy
and fast as on an analog meter or does it leave you
guessing during ESR changes?
