So i can forget the measuring of Resistance  with this meter. but my own fault.

--- End quote ---

There are 2 potentiometers close to the batteries' holder on the PCB, those are used to calibrate the meter. I just tried that once and if I recall, one adjust the AC modes and the other DC (voltage, current and resistance are adjusted at the same time). The pots are very sensitive and I strongly recommend not to play with then if you don't have another good meter to use as reference, the chances are that you will make things worse.

Thanks for the info, can you tell wich poti is for what? My meter is working now good. I have tested the X-Y scope measurement and that is also workung nice. I think it is fot the hobby al good meter for a nice price.

Microcheap:
I like it too, it has its limitations but many times I prefer it over my ds1054z to quickly inspect a signal on a board or make a simple measurement.

Regarding the pots, I know one was for AC mode and the other to DC, but I really don't remember which one is which I should have take note when I had the chance.

amham:
There are multiple sellers on Amazon, anyone know who is selling the latest versions for the 2D72?

Rien:
Hi,
I like to know is it possible to make an 2C72 from an 2C42 with the ST-Link utility I have seen at github.com/circuit-specialists/Hantek-2D72 the bin file and other things.
Is it still possible after flashing this bin file in the Hantek, to download updates for the instrument. I guess thet the meter must be on when the ST-Link V2 is connected to the meter??
Thanks for your reaction.
