 Bigger Bigger  Smaller Smaller  Reset Reset

I purchased the Fluke 116 a while back off of ebay for a fairly good deal.  I haven't had any problems with the meter, but I feel it isn't the right one for digital circuits.  Fluke made this meter for HVAC specialists, and I am not planning choosing that as a career path.  I was hoping someone could suggest a good meter that can obviously measure VDC, VAC, mVDC, resistance, mA (milli Amps), and uA (micro amps).  The Fluke 116 can not measure mA which is my main gripe, and I feel being able to measure mA is a big part in building/troubleshooting digital circuits.  Any thoughts?

Go to circuitspecialists.com, get yourself a nice power supply (or other item of your choosing) and get this DMM for free.

$30.00 does not sound like a bad deal.

Or, the Bargain Level, which still has all the features and good accuracy for $7.50:
BUT: Shipping to USA is probably $10 or more, so not so good for a single item  smiley-cry
http://arduino-direct.com/sunshop/index.php?l=product_detail&p=150
DISCLAIMER: This is in my store...

I looked through about 5 or 6 different low-cost multimeters for one to carry. This has some things I wanted:
- Audible continuity test for circuit checking without looking.
- Transistor and Diode test
- Capacitance measurement
- High current (20A) measurement as well as low (20 Ma fullscale)

So, whatever you buy, look for those too...

I think it would be more like $17.50 to $20 shipped; you can put it in the cart and set a shipping address and see 3 different shipping options.... No commitment to buy...

It might be a little less shipping; I'll have someone weigh it exactly tomorrow...

Stuff like 1 or 2 Arduinos only weigh 50 grams or so each....

That is a good deal. Little light on the frequency counting... but it has features mine does not. I have the UT60E and am happy with it. It cost me $600NM as I recall (600 Pesos)

I use the Frequency counter a lot more than I thought I would have...

The transistor and diode checking capacity is nice. The ability to read capacitors is good.

They are sold in many countries under many brand names.

How's $5 sound?

Looks to have Freq measurement also, see the square wave choice on the dial.

Sounds good!  I'll try to find one like this I can sell for $5.  Shipping is the kicker.  OK if you're buying other stuff too. But this one (I have a couple personally like this) is lighter than the one I sell, (140 grams compared  to 350) so it could go cheap HongKongExpress  smiley

What I really want to find is a much more excellent multimeter for maybe $40 or so...

The one I use is EXTECH brand, model EX330.
Was $35-40, very nive meter.

That and a USB scope, I use www.dpscope.com, all you need for debugging arduino circuits.

Thanks! I'll do some digging for a good price....

Well $50 shipped seemed like a good deal, so I decided to go with the UT60E multimeter.  I chose this one over others because it seemed to have quite a bit of features and the sub $50 multimeters appeared to be missing a stand, which is something I was using a lot with my Fluke.  Not to say a simple stand was the deal breaker, but the $50 USD price was hard to argue with especially when their selling for $70 on ebay.

Thanks for all the input.

I am a big fan of the cheap imported DMMs sold by Harbor Freight (and others.)  They periodically go on sale ("Half Price!") and I picked up my last several for something like $3 each.  (The dollar has been declining and the current sale is $5 each.  Hmmph.)  http://www.harborfreight.com/7-function-digital-multimeter-90899.html

Get two; it's handy to be able to measure current and voltage at the same time.

With a cheap meter like this, you tend to be willing to use it a lot more often.  But don't expect great accuracy; shorting the probes hardly ever yields a zero ohm reading, for instance, and the reading you get doesn't look very likely.

I find I very rarely use the current ranges on my meters.
I'm far more likely to use the voltage and resistance ranges, and the continuity tester.
YMMV
