DCma 2D42 firmware 2020070701

pu6k1n

I have 2D42. FPGA_V07. Updated STM32 with official firmware from Hantek website 2020070701. Current measurement with a cartoon in DCma mode does not work, does not measure, and the point is shifted 1 digit to the left, and how can it measure a maximum of 200 mA? ((. On request 2020051401 the same thing, DCma mode does not work. I put the firmware back to 2019082801 and everything worked for the cartoon as it should. What should I do?

OK, I sent to your email the SN already.

Note that DC and AC mA ranges have the same problem.

Just for the record. Hantek sent me a fw update on the same day and the issue was fixed.

I will also add. I tried to measure ma in DCma mode in the Hantek2xx2 program. The measured current jumps. Firmware 2021010801
