Title: Hantek DSO5202BM: Two bugs, when setting the scan time 80 sec/div
Two bugs are revealed, which are manifested when setting the scan time 80 sec / div:
1) On the screen, the oscillogram runs too fast and passes one division in 13 seconds instead of 80 seconds;
2) Неверная информация в окне "Sys Status":

In this window it is said that all 4000 samples stored in memory are displayed on the screen. However, this can not be due to the fact that a period of about 26.6 minutes (20 divisions of 80 seconds each) is placed on the screen, and 33.3 minutes (4K * 0.5 (2 samples per second)) in the memory.

P.S: Sorry my bad english.

Now it turned out that the oscilloscope does not use all available memory under the oscillogram. In 4K memory at a sample rate of 2 samples per second, an oscillogram with a duration of 2000 seconds should fit, but the oscilloscope stores only what is placed on the screen - 1600 seconds. Why is this happening? It makes sense to do a scan of 100 sec / div instead of a scan of 80 sec / div, so that the entire contents of the memory are placed on the screen and the memory is fully used.

Sir, our engineer will modify these bugs.
Because our engineer is busy with other projects. He's going to finish it in a week.
Please wait for a while.

It's been more than one week and I hope that your engineer is already working on fixing the bugs I've indicated

Sir, I'm sorry.
Our engineer is very busy, and some bugs are complicated to modify.
Only a small problem has been fixed at the moment. Please give me your email to receive the firmware.
We plan to take some time every week fix one bug.
