YR2050 Milliohm Meter High-Precision Handheld DC

[DaneLaw]

There no translation is needed practically.

In 95% of cases, you will use only the 1st menu item (resistance measure), and possibly 5% of the 2nd (wire measure) where both screens are without any Chinese characters. 4th (battery saving) and 9th (contrast) you will set only once after buying, and literally 9th is some kind of useless setting because the one acceptable value for contrast is 5 (from the 0-9 range). Then menu items 6th, 7th, and 8th are not even active... assume they are for dev purposes. And finally, the 10th just contains a ton of calibration values.

You save your contrast settings with "HOLD"
It works as intended on my unit (fw v1.2209) I got the contrast on setting 0.
When entering menu 9.. you cycle the value forward with the button under HOLD and then hit HOLD, to save the value.

Menu 5 seems to be lower & upper limit values and you can plug in these, and you active it at the bottom, where you can cycle the Chinese label for (Off/ON) the front measurement page will then display them (LO/UP) at the left, and the meter will give audio feedback-signal for the ohm reading, with a label on the screen (NO/YES) if its inside the tolerances.

Has anybody tried the 1030+ probes with the YR2050.?

Been really impressed with the YR2050 I purchased a month or two back (my first & only milliohm meter) been running around and testing resistance left & right with the freedom that a handheld unit gives, but the incl. 4wire Kelvin clips are not ideal for certain scenarios, so decided to also pursue the 4-wire probes in the hope they will work with the YR2050, it looks like it uses pogo-pins,.

The kit with a YR1030+ (battery resistance 4-wire tester) was being sold at prices, so it didn't make sense to purchase the 4-wire-probes alone.
YR1030+ with incl. 4wire probes, were merely 21US incl.25% EUVAT & delivery (at the latest sale) but the YR1030+ and YR2050 are two quite different products, so I wonder if anybody has actually validated that the incl. 4wire probes with YR1030+ also works with the YR2050.?

I didn't manage to help you, but because I've taken it apart, I'll post a picture of the two.
When I bought these, I made a mistake and accidentally bought two different connectors.
The two are from the same manufacturer Yaorea, it would not make much sense for them to add a different type of measuring probe to the two devices.
I was thinking about the connections in the connectors.

[DaneLaw]

Yep, it's a shame that the YR2050 is not fitted with the screw-terminal from the other series' or even better 4mm banana jacks.
As USB-A just seems so delicate, and asking for problems down the line.
But the YR1030+ should arrive in a few days., so will check the pin out when it arrives.
Look like there are two different 4-wire probes for these YR1030+/1035+ that I think also would work on YR2050, beside the standard Kelvin clips

There is the side-by-side, what look to be springloaded pogo-pins (picture above #26) and then there is also these (picture below)
- where the probe-pin(s) looks like its, one sliding barrel inside another for the 4 wire expect?.
They cost from around 12½ USD and up, depending on sellers (incl. VAT & delivery) can also be had with the screwterminal interface. (YR1035)  _ https://www.aliexpress.us/item/1005003630321521.html?

The enchanted version is similar to the meter unit of the battery holder. "Battery Stand".
Inside that meter tip there is another isolated meter tip.
It is suitable for four-wire measurements. but since its diameter is smaller, it is questionable how long it will last.
The pogo pin ones couldn't even touch each other because they weren't in each other.
And if you use this a lot, the inner insulating layer can wear out quickly.
The way I look at it, you have to push it all the way in to be able to measure with it.

[DaneLaw]

For the batterystand it makes better sense, as there, I recoon you can lock it in with a firm/tight connection, while as a crude handheld probe I could imagine your reading would be dancing all over, while trying to get a solid connection on both, & holding the inner spring down to align with the outer.

Looks like there are different models..of these 1000 series resistance meters..also looks to be a TR1030?? variant https://www.aliexpress.us/item/1005001624187092.html?

This one seems to be the old OG YR1030 model.

Do you also know this device:

https://github.com/ludwich66/RC3563/wiki

It´s a dedicated ESR meter, using a 1kHz AC signal to measure the equivalent series resistance.

The probes that are delivered with that device look very similar to the YR2050 packages. From my own experience this device works quite well as long as you have reliable contact of all 4 contact points. If one of the probe contacts is weak, the meter sometimes shows an unplausible *LOW* ESR value.

For everydays work I built a set of probes where the 4W-cables are shortcut shortly before a standard 2W-probe-pin.

[csuhi17]

The TR series looks like a different brand to me, maybe "Terrific" and the YR is Yaorea.
Navy blue and red are Terrific.
And the gray and light blue are Yaorea.
I guess "Terrific" is just a rebranded product.
At least when comparing its properties, you can find the same in both brands.

[csuhi17]

The probes that are delivered with that device look very similar to the YR2050 packages.

yes, very similar, only the size is different.
The red Aether BA1020 and the black Yaorea YT1035+.
I think Aether is the same one you linked.

[Phil1977]

Exactly, the RC3563 uses a 4-pin GX16 aviation plug - I think that´s a better choice compared to off-label-USB-plug-usage.

Has anyone ever directly compared the RC3563 to the YR2050? Are the measurement basics (1kHz, ranges, etc...) the same?

The branded Yaorea uses a press-fitting and seems to rely on some ball joints for the lock, IMO it looks to be the preferred way.
The BA1020 and the RC3565 and the likes of it VR1220 etc... seems to use a screw fitting and the same connection I also have on an older cheap Tesla/gauss-meter..

Got the YR1030+ today, its a non-Yaorea branded unit.. it claims 1030B on the screen with FW2.2206 when starting up
there are quite a few differences from this unit I received to the Yaorea YR1035+ with the press-balljoint-fitting
The YR1035+ got a decimal more on the voltage and the menu options also vary.
You got A B C binning functions that you can program, and it also looks like you can adjust the current in menu9 between 200mA and 400mA on this YR1030+, where on the branded YR1035+ its buzzer and contrast in menu9 while you have RS232 option on menu6 on the Yaorea YR1035+.

Went for the YR1030+ for the 4wire probes to be used with YR2050 as the price difference was not a lot between the probes alone and the YR1030+ unit with a set.
It works well with YR2050 so same USB pinout.
