So I have had a cheap multimeter for a number of years which has served me well and will still be kept. However a recent project has finally revealed the limitations of it, namely it is unable to read low ac voltage and does not have capacitance measurement. 


So I am in the market for a new meter between $60 - $170. I am a hobbyist and do not want to spend hundreds, cheaper the better, but I do not want a piece of junk either nor do I want to buy one and find in 6 months it doesn't have a feature I need. 


The features I want are:
AC/DC voltage


AC/DC current 


Capacitance


Resistance


Frequency


Mains safe so CAT II or Cat III


Nice but not essential: diode test, hfe transistor test, auto ranging


 


Any recommendations on brands or suppliers greatly appreciated. Seems to be not many in nz other than Jaycar?


 


I have seen some digitech ones on the Jaycar website but a little hesitant because I have read online the inductance led lights up even when the meter is off and the user manual has no reference to it. Anyone have one of these?

http://www.jaycar.co.nz/Test-%26-Measurement/Multimeters/Digital/METER-DMM-AUTO-4000CT-TRUE-RMS-CATIII/p/QM1551


 


I have also seen this Fluke 106. But seeing them on ebay / ali express I want to be sure I am not buying a fake.

Cant go wrong with Fluke meters that's all we normally use for industrial work. Try the electrical wholesalers for pricing may find a promotion on. Extech is another brand that has a good range of meters.

You wont regret buying a Fluke. OTOH if you are a casual user you might not justify the cost either. Have a look round and see what the low end models go for.

 

Tenma seems to get a push from some distributors too.

Any of those Jaycar meters would be fine for casual home use.

 

Fluke are very good, but just too expensive for your use. The lower price ones usually don't have the range of functions that the cheaper other brand meters have.

 

I have an old Fluke 75 and a Fluke 123 Scopemeter, but I use a Tenma 72-7730A as my main multimeter at work.

I have had a Fluke for years, but also have a couple of Uni-T ones - as far as cheaper brands go, I would definitely buy it over Digitech. Uni-T are actually a pretty solid brand, and are far better than the no-name brand meters you otherwise find on Chinese websites. Here's the result of a quick search on dealextreme - not super cheap, but not too expensive either.

 

EDIT - after a quick look the UT-139C seems to fill your requirements. (Initially thought the no slightly older 61E, but the 139 is better unless you need rs232 connectivity - 139 has "better construction, faster display, input protection, temperature measurement, real fuses, better burden voltages and has a backlight" according to this post)

Have had a deeper look into capacitance and frequency measurements and picked the following based on most versatile measurement range...

 

http://nz.element14.com/tenma/72-7780/digital-multimeter-handheld-3/dp/245066202

 

Not sure what the 45hz - 1khz bandwidth means for the tenma, frequency is specififed at 10hz-10mhz. So it cannot measure 50hz power?

 

http://www.surplustronics.co.nz/products/4525-multimeter-professional-multimeter-ut70a

 

http://www.ebay.com/itm/Fluke-106-Palm-sized-Digital-Multimeter-Professional-in-the-palm-of-your-hand-/331050604918?hash=item4d14275976:g:FY8AAOxyOMdS5iqO

 

My main issue with the fluke is making sure I find a genuine supply as I do not think that model is sold here and the next closest thing specification wise is a few hundred. 

 

I will take a look at a couple of wholesale shops to see what they have.

Over the last 20+ years, Ive had Jaycar & Uni-T (all for hobby stuff)
Work has several flukes (even Flukes can & do fail)

 

My Jaycars still work, but do feel like cheap junk. The cap/inductance test on my jaycars are worthless (just the way you connect the cap never makes good
Contact) .Ive never used the temp function. Ive never use HFE test . Even the cheapest has a (very) basic diode test.

 

My Uni-T are great in comparison to my Jaycars. Ive had 2 uni-t's, I gave away the 1st & bought an up-speced one
However, theses are all just hobby grade. Dave on that youtube link below doesn't seem to like uni-T though.....

 

Some very good MM info on this youtube channel, he even opens them up to check build & safety
https://www.youtube.com/user/EEVblog

 

Get one with a hold function or a min max function (or both)
Get a separate LC meter. Get a ESR meter (or buy a kit) I made my ESR meter from a kit.
Cheap Multimeters arnt(weren't) designed for reading AC volt/amp above quite a low freq , making them near useless for audio. If you want to use the meter
for audio or higher freq then factor that in & check the specs carefully.
That's probably what " 45hz - 1khz bandwidth" means , above 1Khz voltage reading is inaccurate .

 

Just so many fake goods on ebay, chineese online sellers etc. Be prepared to get a fake . They fake everything, even $5 servos :-(

 

"Mains safe so CAT II or Cat III" . be aware that some manufacturers simply lie about meeting this spec.

He is also selling his own branded one now(https://www.eevblog.com/product/bm235-multimeter/) that actually looks quite good for the price(and will just fit into the OP's price bracket).

 

Cannot say myself how good it is as I don't have one yet. But I think it will be my next meter.

 

The only issue is that is won't be available till next month and there have been reports that the backlight humms when on.

Update, Have narrowed it down based on models with wide range of features which means less chance of having to buy another meter in the future.

 

##Tenma 72-7780 (rebranded uni-t 139c) $77 This unit ticks all the box's, my only concern is build quality, the eev blog review of uni-t does not paint a good picture of the brand. Hopefully good enough to safely measure the wall outlet.

Errr, the spec says it measures to 1mV resolution on the 6V range.

 

http://www.fluke.com/fluke/inen/digital-multimeters/compact-multimeters/fluke-106.htm?pid=77005

 

 

 

Interestingly, and this is something to consider in addition to features, the accuracy(uncertainty) is quoted for each range.

 

For hobby use you might not be too fussed, but your needs will vary if you are looking for more than a 'go/no go' meter.

One of the big benefits of fluke is the warranty.
Warranty ends 7 years after fluke stop making the product, with a minimum warranty of 10 years from purchase.

The other great thing about them is they're consistent.
We tested all the meters at work recently. All the fluke meters gave exactly the same measurement in all tests. All the other meters gave varying results (still within tolerance), even if they were the same brand.

Whatever you get, auto power off is a function you should add to your list of features you need.

Amen for auto power off.
A low end fluke would be infinitely preferable to almost anything else, to me.

Mine is still going strong after 20 years, FWIW.

Dave from the EEVBlog has done many many tests on multimeters and endorses / even sells the Brymen BM235. You can purchase it directly from him here.

 

As far as Electronics goes I trust his opinion. He has some damn good videos and really knows his stuff:
