Hantek support emailed the latest FW.
It's a "2023......" version.

Interesting. Glad to hear support is responsive to such requests. Disappointed that they can't be bothered to update their website.

Did someone confirm that the same FW image works for both 1832 and 1833 models?

I did specifically ask support for latest FW for "my 1833C I just got from ali express".
It seems odd that the FW would be hard coded for specific model, because the FW from Hantek site is FW for "183x", so same FW for both models.
Size is still small like their download site version, so I assume some minor changes.

Is this 2023 version specifc to 1833C? Not sure, but the code itself has references to 1832C and 1833C.
I will reply to support asking if that FW is for both 32 and 33.


--- Code: ---[roott@localhost 183x]# strings LCR2023041001.dfu |grep "183"
Hantek1832C
Hantek1833C
Hantek1832C
 Hantek1833C
Hantek1833C
 Hantek1832C

--- End code ---

This is fun...

as currently sharing with Hantek support about 2023 FW (as I do not have from the support) & open calibration issues. As cap at 100khz showing about 8pf after startup, after calibration as close as 0.00XpF bingo...

BUT after restart (switch on & off cycle) I gets again the 8pF as last used seams not to work or the values are false stored. I guess for each freq. & resistor to values needs to be saved differently or not?

So do you have the same issue? Even after 2023 FW release?

I did no testing yet.
Did you try to enter debug mode and then save calibration, then exit debug and reboot?

How do you display the device info in the screen? Or do I need to use SCPI?

would be interesting about rollback to previous version is supported or not.

As I posted (and did not remember this as looong ago :D) https://www.eevblog.com/forum/testgear/hantel-lcr-1832c-unlock/msg3596003/#msg3596003

As worked with debug mode, but IMHO this is shit, as to connect with a PC & App.

Please let us know how the new worked as whether the open calibration saves now or not or only in DEBUG mode.

May add a small cap for getting OFF calibration value and then test it with calibration(without the off cap) and switch off & on again.

Anyway, complained on Hantek support about this as wee need a solution without any PC & App. May a special key combination.
