Multimeter

[geoff]

Angle of dangle, what else ?

[The Medway Handyman]

The angle of the dangle is equal to the heat of the beat when the throb of the knob is constant.

[Dave Plowman (News)]

Right. Never seen a Fluke like that.

I doubt I could be bothered since most DVMs (and my Fluke) measure current too.

[Graham.]

Can it do ESR and "count" frequency?

[Andy Dingley]

No, I've got a teenager doing A level physics for that!

(Fluke fuses are over a tenner a pop)

[Andy Dingley]

Get several. Upgrade as you need new features. Start cheap. Finish with a Fluke (about 25-30 S/H on eBay)

Do try to get one with real sockets and a decent set of cables though. It's very useful to have both prods and croc clips easily available.

A while back I bought myself enough of megger to do PAT testing with. No idea why I bought this, as it cost 30-40 eBay quid and I already have a stupidly expensive Kewtech tester of everything (with cal papers too). However I now use this for pretty much all of my bench & DIY electrics. Does voltage and moderately low resistance too, which is 99% of everything I ever use a DVM for. As it also proves out scrap washing motors etc as vaguely safe or provably hazardous, it was money well spent.

now I believe.

[Dave Plowman (News)]

I'd guess.

[Dave Plowman (News)]

It does frequency, yes. I have a separate ESR meter. I'd admit to not having seen an ESR function on a DVM, although I suppose it is possible.

If you can't get IPA, would any best bitter do?

[Part Timer]

Once another form at school (GCSE chemistry) were doing a practical where they were coating keys etc in copper by electrolysis. The instructions they followed were by a teacher without a clue how to measure current. Cue 28 fuses needing replacement! I think they were the ordinary glass type, but it still took a physics teacher and technician ages to change them.

The current replacement, Fluke 114 "Electricians¹s Multimeter" also does not have current ranges BTW.

Was that pun deliberate?

There's two sorts of IPA. One is eminently quaffable, the other isn't.

[Dave Plowman (News)]

Quite. Why would an electrician ever need to measure current? ;-)

[whisky-dave]

Oh so it's not realy made for use as a door stop, but it works so well .....

[whisky-dave]

I've had that, last year I replaced something like 25 20mm 250ma fuses in = our stock DMMs. =A311

problem is the lab sheet says mearure the current coming from the power= suply so a lot of students connect the DMM in ameter mode across the PSU t= erminals, Obviously they don't get a shock, until I hit them for doing it = ;-)

But my prefered cheap meter is....=A318

has an included thermocouple for measuring temerature.

[Tim Streater]

1) don't these things have popup breakers rather than fuses? 2) Haven't these kids had a lesson before they get their mitts on the kit? Doesn't Teacher go through where you'd measure current as opposed to voltage?

[Andy Dingley]

Doesn't matter. Multimeter fuses are super-fast. One reason they're so expensive.

[whisky-dave]

I don't think that's true, certainly the ones I've used aren't super fast i= n fact They might be more expensive becuase of supply and demand. The fuses I've used to replace the ones in the 328 meter=20

about 20p each the fluke branded ones are more expensive.
