LC Meters, in Australia

sparkless · 22nd July 2009, 05:08 AM

I've been searching the stores for a cheap LC Meter & I have found a couple.
The trouble is these meters only measure inductance from 2mH upwards, and I want to build some inductors with values of around 0.6 to 0.9 mH. Do any Aussies know where a suitable meter can be purchased in our fair land at a reasonable price?

Thanks

Steve

How about buying a Woofer Tester?

It's good at measuring inductors. And of course it's a driver impedance tester, so if you keep building speakers, you'll need it anyway.

Search "WT3" in Parts Express.

Jaycar have a couple of DMMs with L C capability; whats your budget

Same boat, built this.
If you can solder you'll be fine.

I have seen one Jaycar model, cat # QM 1324,
Inductance, capacitance, Freq, $49 95,
but the inductance starts from 20mH up.

If you can see another jaycar model suitable, post the cat#, thanks.
Another altronics model was about the same price but started at 2.0mH up.

Doesn't measure capacitance!

Looks Ok, was it that easy to build ?

I had that jaycar meter.
Threw it out after two weeks.
Slow and very unreliable.

EDIT, yup, very easy.
Will take some pics if you like.

Thanks MM, another reason not to buy it.

Pics, yes, that would be good, thanks.

MadMutt · 22nd July 2009, 07:59 AM

doing pics now, can send you hig res ones if you want to give me an email...

Ok, here's an internal shot.
So simple.

IGNORE the yellow wires.
The lcd module has a backlight built in, but is not used in the kit.
I like to see what I'm reading in all lighting so I've wired up these back lights.

Yes, looks easy enough. Pity though it only measures up to 0.8uf.
But the inductance range is good.
