How do I check if I'm getting the right readings I wonder? I need to check if my meter is actually that precise.

i think i gave you the answer in the post above maybe you use other messurments in your country you can read about the thematic specific resistance an learn how to show if your meter is precise you can also get a resistance and measure that

this things you can measure dont know specific english word for that

i know it just from personal experience i never read the technical details but this one showed me precise the natural resistance off 1meter pure copper whit a cross section of 1mm at 30 degre celsius at 0.175 - 0.180 so it was safe use for me

I edited that post, which was just wrong statements. The spec clearly says it's precision is =-1.6% of 400 ohm with resolution of .1 ohm.

Yes, that will work. Get resistors with resistance in the milli-ohms, and measure to verify that the meter is that precise.

I was digging around looking for precision multimeters for resistance measurements, and the ones to look for are the "Internal Resistance Meters" based on your post. Is $40 a good price for range of 0-200m ohms? I have no idea how the resolution is (doesn't give me an error/tolerance spec), but here is the specs

Battery Voltage : 0~1.999/ 2.00~19.99/ 20.0~50.0V
Resistance/ Battery Internal Resistance: 0~199m/ 200m~1999m/ 2.00~19.99Ω
Negative Polarity Indication: “-”shown on the display automatically
Operating environment: temperature: 0℃~+40℃
Relative humidity :<80%
Temperature Coefficient: 0.1×（specified accuracy）/℃(<18℃ or >28℃)
Battery: 9V battery, 6F22 or equivalent (1 piece)
Size : 150x83x44mm
Weight : 315g

yes, the path for budget good resistance precision at miliohms are the resistance/battery internal resistance testers.
these will show 3 decimal points (miliohms). although precision is not specified in this case, it will probably be from 1 to 5 mOhm for low range resistance (0-199m).

This is the one. http://www.all-sun.com/EN/d.aspx?pht=1132

Crossing my fingers that it's precise. Looking for milli-ohm resistors to test it out now. What do you use for testing the readings? I'm thinking about buying SMD resistors to test.

Now I'm concerned about leads not being easy to place on the cable for good readings. I can use alligator clips, but that will add resistance to the reading. I wish the leads came as minigrabbers.

got some assorted sets of resistors, but they also have a tolerance range, so you can't be sure of true accuracy of your DMM.
i prefer to read detailed reviews made from experts with top notch gear, which include full and real accuracy measurements.
that's why i ended buying YR1030 (it can be found for around $30 now). https://lygte-info.dk/review/InternalResistanceMeterYR1030 UK.html
resistance accuracy (less than 1mOhm for below 1ohm loads):

DC voltage accuracy: (3mV at 1V, 10mV at 2V)

index of DMM reviews:
https://lygte-info.dk/info/indexDMMReviews UK.html
https://lygte-info.dk/info/DMMReviews.html
battery internal resistance meters can be found in this section:
https://lygte-info.dk/info/index UK.html

the problem with these battery internal resistance meters (yours and mine), is they only measure DC voltage besides of resistance.
and you need an accurate AC voltage meter for measuring IEMs or sources. i have to use different meters for accurate resistance and AC voltage..

You know what? I decided not to get the Allsun meter I linked on my previous posting.

I decided on the one you recommended, ZT109. I know it has resolution of .01 ohm, but I find that's all I need because the typical cable resistance values are between .1 to .5 ohms, and it's not really necessary for me to know down to .001 ohm of resolution. Also the ZT109 is an all rounder for AC voltage reading as well. I've calibrated my SPL meter with a different meter from Harbor Freight I got that reads up to 20kHz AC to RMS, but I'm curious how well the ZT109 does for my calibration? $24 is a bargin for .01 ohm precision. Nice find!

I ordered a set of alligator clip leads for it as well. I think alligator clips would work best. Let us know how the battery tester fares. I'm curious about it. Looks like your link are from Denmark, and I'm guessing you're from around that area? That's where GRAS is from (you probably know that).

yes, ZT109 is cheap and allows you to measure resistance and AC voltage with decent resolution.
but remember to subtract resistance of leads from your resistance measurements (that's the caveat of not using 4 terminal leads..).
wait, i'm going to locate the best cables + alligators i found (minimal resistance, stackable, good true copper rather than brass or other alloys)

You may want to check out Probe Master leads/alligator clips/etc - I bought a few pairs from them for use with my Brymen 869s and they are top notch and fairly affordable:

Just in case you were not familiar with them...

i come from and live at Spain; i know some excellent guys from Denmark, and the guy from the links is an extraordinary measurer and reviewer of power gear, his site is highly recommended.
yeah, GRAS is Danish, and also is Brüel & Kjær. great country for accurate measurers

these are the cables (banana 4mm), retractable cover, stackable:
https://www.aliexpress.com/item/32798647058.html

you can plug the 4mm bananas into these quality copper alligators:

these are small copper clips (they don't scratch plugs, they are softer but less secure clipping):

i also own and like these DMM leads:

Enjoyed reading a lot of this thread. Any of you using these cables with the Focal Stellia? I'm looking for a 4.4mm balanced cable. These headphones already have an outstanding level of detail, clarity and soundstage. Bass is also very good, but it would be the one thing I'd add a little more to if a cable could help there.

Seen these on eBay and they get great reviews, but I'm betting the connectors and actual cables are still sourced from China. I'm presuming their is a close equivalent on Ali Express?

The wire used in that cable comes from Taiwan, Neotech up-occ (superb). the plugs are Neutrik (Lietchenstein, but you can find them all around the world) for 6.35mm or XLR, or Rean for the rest (Neutrik subsidiary, made in China, very cheap, not same quality as neutrik).
If you look for bolder bass, pure silver up-occ is not the best choice.
You can find same brand of wire (up-occ, excellent) in cables 173-174 (pure silver + 1% gold alloy), or 170-171 (frozen up-occ copper litz), or 165 (frozen copper, no litz), and 169 (frozen copper and silver plated copper mixed) in my list of cables, with far better plugs (beryllium copper, gold and rhodium plated for 170-174 cables, instead of rean/neutrik gold plated brass), and far lower price.
There are pics, comments, and links of these cables there.
If you like up-occ wire (for deeper stage, more separation, detail, and imaging perception), but want the one with more bass sensation, you should consider cables 170-171 (up-occ copper).
I'm using cable 171 with HIfiman Ananda right now, and it's great (using mmcx/2pins to 3.5mm TRS adapters).

Thanks a lot. Post of the day

thanks. if you want the cable be dedicated to Stellia, you can choose the 3.5mm plugs you like from their stock, and ask the manufacturer to use that termination (kind of custom).

another option is what i'm using: cable ended in 2pins or mmcx plugs, plus adapters from 2pins or mmcx to 3.5mm TRS. this way i can use the cable with iems, as well.

At $800.00 for 3m would these really fit into the ...
Low end. Cheap. Generic. Otherwise bang for buck cable thread???

Definitely not. Reread my post and excellent answer from hakuzen
