My copy has arrived and it works perfectly.
In the version I ordered, the minimum current that can be set is 0.2A - probably this is how majfrendy solved the problem mentioned by a colleague:

An additional change in relation to the item tested by the author of the thread is the indication of the average battery voltage after the end of the test (not the current one).
This value for Li-ion cells is displayed only after exceeding 0.1Ah.
It is useful when we do not know what the rated voltage of the cell is - 3.6 or 3.7V. But you have to remember that heavily worn cells will significantly reduce this voltage.
I also tried to measure the capacity of a 12V / 44Ah car battery, but with a current of 0.1C = 4.4A and a voltage of slightly over 13V, the load works at the limit of the permissible power and the heat sink gets very hot.
I postponed this measurement until I improved the cooling by means of "dips".
