1) So far, it has not produced such an error for me.
2,) I didn't notice, it's true that you have to calibrate the open and closed states separately, but for me, if I do it in the order 1. closed 2. open, the resistance of the measuring cable remains 0 in DRC mode.
If I measure with an alternator, i.e. in non-DRC mode, 100-200mOhm remains, I think it might be a property of the measuring cable...
The factory Kelvin clip is not the best.
3) I don't have this error either.
In the case of calibration, if I calibrate in non-DRC mode, it lasts for 30 seconds and resets the frequency to 100Hz, all the others remain at the settings I left.
If I calibrate in DRC mode, it is done in about 4 seconds.
if I change the Range to another value, e.g.: 100k and calibrate one, it resets, i.e. it shows 0 Ohms, but when I change the Range to 10k and then back to 100k, it shows the wrong value again.
What I wrote as an error is the incorrect measurement of high-value resistors in non-DRC mode.
At 10kHz and 100kHz, it incorrectly measures high-value resistance.
There was another one that I thought was a bug, but it wasn't.
The RECord function does not work if the measured value has a negative sign.
I don't even understand :Đ
However, looking at the pictures, your version and mine are different.
I have the Blue, you have the yellow.
Things on the display look a little different to me.
It looks like this
