Ok so I'm in the market now for a cheap LC meter. Doesn't have to be the most accurate thing in the world, just needs to give me a preferably +/- 5% inductance measurement on all the coils, chokes, filters, and toroids I have laying about. Budget is around $100 tops. Kits are OK. Would prefer capacitance measurement greater than 2000uf but smaller is OK.

Re: Recommend a cheap LC meter...
If you are going to do a lot of inductor testing, you should get the one that can do ringer test also to find out if it has shorted turn.Never stop learning

Re: Recommend a cheap LC meter...
After checking out my choices in the price range that I had to spend I ended up snagging what appears to be a NOS NIB Atlas LCR40 off Ebay for around $90 (almost got one at auction for $50). I say NOS because this unit does not have the disconnectable clips like the newer units have.
In any case this appears to be what I need... capacitance range from down in the picofarad range up to 10,000uf, inductance range from 1uH to the mH range... perfect for all those toroids and bobbin inductors laying around that I have no clue what the inductance is.
Finally I might could get some of those DC-DC SMPS converter circuits completed and even get a few transformers wound too.Comment

Hi all,
I was looking to upgrade my main multimeter (Asita MD591) with something that has more features. I'll use it mostly for board diagnostic and diy repairs. I've been eyeing out many of those multi-function ones from Aliexpress but can't seem to make my mind up. Here are the features that I'm looking after:
- Autorange
- DC volts up to 30V
- Accurate Resistance
- Diode test (Beep mode)
- Frequency up to 200MHz
- Capacitanze up to 5000uF
- as cheap as possible
Other functions are not needed but those which are needed... -
I read EBOOK of Testing Electronic Component and found that
"In order to test the small blue resin coated ceramic disk capacitor which has 104 50v specification,it is possible to test this small ceramic capacitor by making use of analogue meter.
Set to times 10Kohm that has 12v output from the probe to check disorder of ceramic capacitor.
It is not uncommon that testing result of digital capacitance meter is okay,But It show shorted reading when you check it with analogue meter."
Is it really possible to test small ceramic disc capacitor with analogue... -
have been looking at earth leakage clamp meters and its like a minefield out there . i wondered if anyone here had bought one that actually works properly ?... -
I have had with regular AA batteries that leak this meter is expensive new I already replaced the battery battery clips once and the same thing happened again and I am tried of so it is getting modified to accommodate lithium ion batteries that are the same size excluding the positive terminal and removing the battery clips I will have enough room for the BMS protection board
I going to put 3 lithium ion battery in parallel with the BMS protection board and a way to charge the battery externally and heat shrink the battery pack and use a JST connector so I easily remove the battery... -
Hello, I have ESR70 and this schematic was sent to me.
1.Can I use some non electrolytic cap so connection polarity does not matter?
2.What cap would be best? super low ESR and small size would fit in standart RCA JACK?

3.Is resistor needed, why?
4.Anyone compared such measurements with proper meter for battery internal resistance?...
