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.
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.
