Multimeter recommendation?
-
I have to agree... I think you'll need at least one Fluke.:yellow_heart:
-
Temped by EEVblog BM235 Multimeter especially given it comes with some nice silicone leads.

The flukes are very nice though!

I'm looking for a one that's a bit cheaper. And so a voltcraft VC 130-1. Is that a decent multi meter for a hobbyist?

Anyone reading this post, and thinking of buying Multimeter , I recommend buying a like this one,.
Because you cannot measure AC current using that traditional multimeter like this one.
Accuracy of clamp is greater than the traditional one, you can also detect the flux or EMF using clamp meter. It will be very usefull in detecting live wires with current and in the projects related to coils as it can detect EMF. -

I have a completely automatic one, and I love it. It doesn't have a dial you have to turn to determine sensitivity.
All it basically has is an on button and two leads.
This gives me much more assurance that I won't fry the multimeter, so I use it a lot more.

OK, my best recommendation is Brymen BM869 (with logging) or there is a model without logging.
I have also supported a kickstarter project for a new Dave's multimeter EEVblog 121GW - https://www.kickstarter.com/projects/eevblog/eevblog-121gw-multimeter
There is another model EEVblog BM235 which I can highly recommend.
I have changed my mind about Vichy VC99 multimeter. Mine failed after a year and the build quality is just poor - you would not want to test even 240V with it. However, it has been very accurate in the beginning and extremely cheap.

@nca78 for such a low current the best bet would be EEVblog's uCurrent
https://www.adafruit.com/product/882@alexsh1 yes and no. I measure at 3.3V then run my low power nodes on a button cell so below 3V voltage, so I measure current a bit higher than the real one when node is on battery and I'm sure the battery life I calculate will be met. I don't need an ultra precise measurement I just need to know if I'm in the expected range or if something is wrong.

@nca78 Sometimes I need to measure current as low as 2uA. I do not think I can do that with my multimeter. So uCurrent is a good investment from my perspective.

@alexsh1 https://www.openhardware.io/view/380/Micro-nano-ampere-meter-double I think it is a good alternative from a cost perspective

I already had a Fluke 72 (old one with no current range below 10 Amps).
So for better accuracy, I purchased an HP 3478a digital multimeter on eBay for about $140. It gives me all the accuracy I want (but probably don't need) and has 1 µA resolution (accuracy is somewhat less but for tweaking battery usage stability makes it usable.
Of course it is not as portable as it needs mains power.

I just realized I forgot to report back. I bought a multimeter called pm18c. The temperature sensor is very fragile - broke almost immediately. But the rest works well. I still use my old small multimeter a lot though, the pm18c is a bit bulky.
Big thanks to everyone for the input!
