Why has it got to be Cheap !!
Even a very good one is not expensive.

That's a new one to me. ESR meters and schematics for them seem
to be popping up like mushrooms these days. Which is good, because
they do save a lot of time when repairing gear which is more than a
couple of years old, or which runs hot internally.
I just did a Google search for -- ESR meter site:.uk -- which
brought up a variety of sources for them in England.
Good luck.

Bob

Thanks Ross.
I collaborated closely with EVB in getting that version of the
meter finalized. It does have more protection against charged caps
than my original circuit (big fat diodes). The components are high
quality, plus it uses the very bright red Kingbright displays I
originally specified, whereas the DSE meter has cheaper
moderate-brightness orange displays.
I think the EVB meter's really good.

I've seen posts on the ESR meters here and there and though I've thought a
few times of getting one, haven't as yet. Who distributes the meters in this
thread - of Mr. Parker or whomever? I seen him list EVB, I'm not familiar
with them - at least not to my ever growing feeble mindedness and subsequent
knowledge or lack thereof. What sort of price tag are they carrying. Also, I
seen one made by Tenma, is it of any quality? I'd like to buy a good one
when I do go to buy one. Any I should look at if I can't find "a" particular
model/brand? Any I should definitely steer clear of? Any particular specs it
should have to make it stand out over another model?

I notice that the ESR comparison page states that Anatek ceased to
carry the Dick Smith kit
http://www.dse.com.au/cgi-bin/dse.st...uct/View/K7214

"Anatek experienced degradation in the components supplied with this
meter and stopped carrying it in March 2005."

Without knowing who was making up the kits Anatek was stocking it is
not possible to know where the fault lay with regard to the alleged
"degradation in components". Bob Parker, the designer, specified high
quality but readily available components even in the Mk1 version
described in Electronics Australia, January 1996. Resistors were
specified as 5% (which would have been carbon composition), except for
the critical units which were 1% metal film. Capacitors were either
MKT film, RB Electro's, monolithic X7R or ceramic NPO as the case
required. Given the possibility that the Anatek kit supplier may have
deviated from the original parts specification it might have been
possible for the degradation to occur, but it would not have been the
case if Bob Parker had any say in the matter. At the time of the Mk2
release in April 2004, over 12,000 Mk1 kits had been sold, most being
made to customers outside Australia. Surely this is testament to a
well designed and reliable unit. With the release of the Mk2 kits in
April 2004 all resistors are now specified as 1% (which means all
metal film) while all other components are still high quality units.


The quality problems we encountered were poor pc board tracks and
holes making reliable assembly difficult. There were also missing
parts. That was more than a year ago, so perhaps those problems have
been solved.

At the same time DSE mislabeled a large shipment to us but charged our
credit card anyway. We found out about the mislabling when one box
out of the four arrived by some miracle. It had no city, state or zip
code on it and the street address had no number, just the street name
but somehow made it to an ajacent town whose name is the same as our
street name. The postmaster looked AnaTek up in the phone directory
and found us. That is how we saw the mislabling.

DSE insisted that we pay for the entire shipment and we refused and
disputed the charge. The shipment costs were charged back to DSE who
now refuse to ship with us as if all this were our fault.

Therefore, we can no longer offer the DSE items. Frankly, I miss
handling Bob's designs as they are good, but I do not miss DSE.

You don't need to spend up big to measure capacitor ESR. You can do
it for about 99 cents!

Years ago I wouldn't have said anything negative about DSE's

couldn't-give-a-damn attitude of the people who replaced Fiona is so
well known that I'm not going to defend them.
That's the reason that I've got the EVB version of the ESR meter at
the top of my ESR meter web page. If DSE loses a large chunk of their
overseas sales of the kits, it's because they brought it on
themselves. I just wish that EVB would make and sell that version of
the meter in quantity at a sensible price.
Thanks for your nice thoughts about the basic ESR meter design.
Much appreciated.

Doug Jones' Cap Wizard's a great instrument. I've never heard a
single bad word about it, but plenty of praise.
All I'm saying is that any kind of ESR measurement saves an amazing
amount of time in a repair situation. Just ask Larry Dishman who
sometimes pops up here, who's been a fan of the Creative ESR meter for
20 years or more.

Bob is right, as usual. The most important feature of an ESR meter is
that one is on your bench. They all work, have different features,
strengths and weaknesses. Some of it is personal preference.

For years we carried both the DSE (Bob Parker's design) and the
Capacitor Wizard. When customers asked for a recommendation between
them I always said that it came down to personal preference for an
analog meter and a digital readout.

The Cap Wizard has the additional advantage of an audible beep which
allows you to keep your eyes on the unit under test and move along
from cap to cap. The DSE unit has a price advantage. Make your
choice.

The Cap Wizard is also sensitive to charged caps. The repair is not
hard but that is non-productive time. That is why we developed the
Savr circuit for it - lets the meter work but protects up to 400
volts.

I might as well add a word about some cheap imports that have been
manufactured in China and sold by (for instance) a big electronic
wholesaler in Toronto. Those ESR meters have major problems
with protection... one should implement input protection, else its
only a matter of time and a waste of Can$ 39.95 since they are
completely toast after an ordeal with a charged capacitor.

Hi Bob
I built your kit a few years ago and it has been a great addition to my
shop. It still amazes me the dead sets I get working without a
schematic by just poking around a SMPS and finding a high ESR cap.
Prior to getting this meter I would resort to other tricks. I would try
powering up and after fifteen minutes or so feel the caps around the
power supply. Sometimes a warm one turned out to be the culprit. Then
there was always the hot bridging method. Lots of sparks and excitement
At least once you will inadvertently reverse polarity. I wiped out a
regulator and scared the crap out of my wife that day. With my meter
though it doesn't lie. Among many other things we do here, I rebuild
apartment house intercom amplifiers. These things sit in a lobby wall
for twenty years and will suddenly start sounding like crap. I find
dried up electrolytics with my meter almost every time. Its a quick
profitable repair. and the building managers love it too as I rebuild
their equipment at a fraction of the cost of new. One serious concern I
have though is that on more than one occaision I have discharged caps
through the meter . Apparently, and luckily these were not charged
enough to damage it but seeing an arc even a small one through my meter
sure disturbed me though. I read somewhere in this thread about the
installation of two diodes. Could you please tell me the specifics of
this modification? Thanks very much and best regards, Lenny Stein,
Barlen Electronics.

Hi again Lenny,
I know what you mean about the "hot bridging" technique. It's not
for the faint-hearted! There's also a fairly high risk of damaging
semiconductors in the circuit, as I seem to remember happening to me a
long time ago.
Regarding the idea of adding extra diodes for protection, this is
what I wrote about it in the Mark 2 kit instructions:
"Heavy-duty protection.
To provide greater protection
against connection to charged electrolytics,
some kit builders have
connected an inverse-parallel pair
of 1N5404 (or similar) high-power
diodes between the test lead sockets (jacks).
If you’re the kind who’s likely
to connect the meter to the
120uF input filter capacitor of a
240V-powered switching power
supply without checking that it’s
been properly discharged, this
modification is for you.
Reportedly, this protects the
meter quite well, although it can
result in the probe tips being blown
off by large charged capacitors.
The resulting surge current can
also damage the charged capacitor
and the power diodes themselves.
However, without the diodes, the
resulting 600A current spike
destroys the microcontroller (IC2)
and damages C6."
Anatek Corp was selling a little protection board for the DSE ESR
meter, and probably still is. It's much kinder to the meter and
capacitors than the above brute-force idea. On the down side, it adds
a small amount of resistance to the test lead circuit, making it
essential to use high quality low resistance test leads.
I hope this gives you some ideas to think about. I'm delighted that
the meter's been assisting you for so long.

Regards,
Bob

Thanks for the interesting suggestion, Max. These days I'm
working for someone else, and I wouldn't begin to have time to get all
the bits and pieces together and sell them as kits or assembled units.
DSE is shooting themselves in the foot by upsetting buyers of their
kits in quantity, and EVB doesn't seem to know anything about
marketing.
I'm not sure what to do....

Cheers,
Bob

In "PopTronics" (USA) July 2001, pages 25-28 there is a build it yourself
design that uses a few common parts and has full protection. It claims to
test in circuit from 1 uF on up.

I remember that one quite well, because of the absurd number of
errors in the schematic. Don't even think of building it until you've
got all the errata notes which came out in subsequent issues.

Yes.

I contributed articles and computer programs to several magazines back
in the '80's. They insisted on double spaced, non dot-matrix, hard
copy on non perforated paper, and a floppy with a working sample of any
programs. It wasn't easy (for me at the time) but I complied and the
published work was always wrong. I spent a lot of time sending in
corrections.

Never made any money but enjoyed seeing my name in Radio-Electronics,
Popular Electronics, HUG and MicroComputing magazines. Lucky I had a
real job.

It really isn't my fault that they are not around now.

Well perhaps you need a business manager Bob. I would miss new
Hampshire but Sydney looks beautiful. Do you have skiing in Austrailia?
I roller skate and bike too actually,( when my arthritis isn't
bothering me).
But seriously, you have designed a great product.It would be a shame if
it were not to reach its full potential or worse, to fall by the
wayside due to the inept actions of others. Lenny Stein, Barlen

Hi Lenny,
Australia has everything the USA has, except NTSC television,
left-hand drive cars and 117V 60Hz electrical power.
A few hundred miles south-west of Sydney there's more skiing
country than I could describe. You can do all the other things too.
If you're interested in having a quick peek at what Sydney looks
like to an electronics technician (me) walking the streets and parks
etc with a digital camera, have a look at
http://bob.parker.web1000.com/sydney/ (if that server hasn't failed
again).
Thanks for your supportive thoughts about the ESR meter. I think
that things aren't quite bad enough to make it hard for someone to get
their hands on one if they really want it. Companies like EVB,
E-Leader and John's Jukes are making sure of that.

Regards,
Bob

G'day mate!

Nice pix. What the heck is that critter in front of the hospital and
what is he doing - remember this is a family newsgroup.

What, no baseball diamonds? I thought Australia was civilized ;-)
