I posted my 10K test results with my 1833C here. I did not capture the theta angle though.
_Yuri:
I recently bought 1832C on Aliexpress and unlocked it for 1833C as described above.
Tested 10kOhm at different frequencies and got the same problem with theta, at 50kHz and above it increases to 20 degrees. The resistance increased, to 10.5 kOhm only.
When calibrating 50 kHz and above, it switches to fast, It seems it is not calibrated on it.
I downloaded and flashed 1833 dump (https://www.eevblog.com/forum/testgear/hantel-lcr-1832c-unlock/?action=dlattach;attach=1903665), then LCR2023041001 (https://www.eevblog .com/forum/testgear/hantel-lcr-1832c-unlock/?action=dlattach;attach=1991305).
After this, calibration takes much longer and, the resistance and theta remain correct for all frequencies when measuring a 10k ohm resistor.
Didn't touch the capacitors.

Dear Yuri, i haven’t tried anything yet, but this makes sense, the calibration data must be in the flash rom of the 1833c. Damm, you are a genius. A true genius.
I will try tomorrow morning.
Here is the correct link for the latest firmware https://www.eevblog.com/forum/testgear/hantel-lcr-1832c-unlock/?action=dlattach;attach=1991305
Can you just tell me how to flash 1833c dump file? Just use the DfuSe Demo software? Should I set some parameters or just start upgrade?

As using a "genuine" Ali Express 1833C from the given Hantek distributor :-DD
For my issue as not saving the Cap calibrations, I asked the Hantek support about:
[1] Fix or solution for this issue
[2] Whether the 2023 FW release is "genuine" and save to load
As for [1], a lady form Hantek asked back about the used ambient temperature :phew:
than absolute silence:
This means for me, Hantek is now on my BLACK LIST for any products of them as support in questions. :palm: :palm:
Or it simple means, the LCR 183x is NOW or a DEAD unsupported product :box:
Just be warned about!

All done. Thank you Yuri.
