MISSING: Bob's ESR meter ??

"Franc Zabkar"


I don't know why but the first search will be successful if you avoid
"All of Site" in the drop down list.

** Even if you click "Product Categories" - "Kitsets" - "Kitsets - Test
Equipment" there is still no sign of the ESR meter.

It was when I got to that stage yesterday that I decided to post the
MISSING query here.

I looked at both kits in DSE yesterday, and the MK1 was advertised
as "ESR and low ohms meter", whereas MK2 said only ESR. Is that
just a labelling thing, and MK2 does low ohms also? MK2 was a bit
more expensive, and I thought I'd postpone the decision until after
I'd asked. I don't have an immediate need, but if/when I did need one,
it'd be nice to have a kit with panels etc... so I thought I'd grab
one in case DSE drop it.

** The Mk 2 is simply known a the "ESR Meter " .

Like its predecessor, it will measure low ohm resistors ( <100 ohms) but
NOT lengths of wire or cable - inductance screws up the reading.

What BOTH will do but nobody tells you is test the ESR of common small cells
and batteries - rechargeable ones and others.

The relative condition of a AA, AAA, C, D or 9 volt types and any button
cell ( silver oxide, lithium etc) can be assessed in a flash by comparing
the ESR reading with that of a known fresh cell.

Cooool! Thanks for that.

At least in my case I have to be careful in testing batteries. I put two
anti-parallel 3 Amp diodes across the test probes inside the ESR meter
case. I think there is even an optional instruction to do this in the
notes that come with the kit. It is for those who forget to discharge the
caps in a SMPS before testing them, and I can be pretty forgetful.

When I want to test a battery, first I get a large electrolytic, and test
that with the ESR meter. The I put the electrolytic in series with the
battery to be tested (plus terminal to plus terminal), and I test the ESR
of the combination.

Just out of curiosity I went to www.dse.com.au & tried "K7214", "esr" &
"esr
meter" ..... every one of them came up with a picture of the Bob Parker
ESR
meter.



** Each one failed, just now, when I tried.

Hmmm, it seems like it's something to do with the DSE site.. Reading through

I'd be careful doing that. I have the Mk1 vers and it has back to back 1A

diodes across the output/input and the Mk2 have beefed that up (4A I think) so I
don't see how it can check batteries (with a 'true' reading anyway).

** It works just fine - I won a nice prize from EA magazine for
describing all about it in their CDI pages.


Do try to get your facts right in future - Stan.
