Hioki LCR 3532-50

EDIT: Title changed.

Hi,

I have this beautiful unit, a thread about it can be found in the repair section, and I am looking for these documents.
I just can not imagine that really no one but Hioki himself has these documents. :P
And Hioki consistently gives nothing out. ::)
Repaired I have the LCR meter already in the sense of the main problem solved.
However, the display and especially the touch panel are damaged due to age.
The latter I had bought "new" on ebay, for expensive money from China.
Unfortunately, it was probably just as old, the contacts have dissolved after several plug cycles. >:(
The display itself is also offered and also very expensive, around the 300€...
This is all too much for me, even if you get an excellent measuring device with frequencies up to 5Mhz afterwards.
Therefore, the idea of giving the device a new display with touch input becomes more appealing to me.
But I would need at least the schematic of the controller board.
Therefore the question for the documents - It does not even have to be the 5Mhz variant, because it is about the HMI, which should be the same for all models from the series.

Hi,
Next week I have a few days off after the holidays and mainly I want to take care of the Hioki, the problems have remained and I don't see the point in spending money again and buying a touchpanel in unknown condition from the China man for almost 200€, not to mention the display.
What's more, the yellowed front panel, which I had managed to get halfway bright after some painstaking work, is as yellowed as before.
So the tasks are as follows.
- New input system
- New front panel
Regarding display/touch panel:
The original system consists of a touch panel with resistive pressure points, which is mounted in front of the LCD display.
The LCD display itself is a monochrome 320x240 in 5.3" size.
Without a schematic it will be very difficult, what I found out is that the display itself is "raw", it expects data in 4-bit parallel format.
This is provided by the Epson chip on the controller board.
This in turn gets its data from the µC, which also processes the input from the touch panel.
It will be very hard to emulate the previous input/output system with today's touch displays.
But my Hioki has a built-in RS232 interface.
Maybe I can "hang on" to it with a new touch display.
The software for reading/inputting from the interface can still be downloaded from Hioki, I'll have a look at it in a few days, I had to buy an adapter first.
Why do I want to go to all this trouble?
Because a comparable device today easily costs €5000 and because I want to work through a "trauma". ;)

only solutionsfor stand alone ...  or unless you convert it to a windows driven machine ?

as you wrote
reverse engineer the protocol / data bus between the mcu side to the lcr side,  you could mimick  touch and controls with other platform  ... BUT you may or would need to imlement all the calculations ...

OR

get some hmi interface with serial port and build your visual interface to send commands / receive values ...  many brands and companies, some have "easy to do" tools, protocols / commands / examples etc ...

you have some Nextion, some arduino compatible  .... lots of choices

in the end you have an head controller and the measurement unit ???  like Chroma lcr's who goes to 5 - 10 Mhz ...

but in the end  no easy solutions

personally i would try  HMI  route

or  try some tablet pc ????  touch screen at 10 "   ??

usb to serial ....  bam    it works   loll

started the pc software on win 11 x64      but since no lcr on com port  ... it closes

If I get full control and same displaying via the software it won´t bother me to do it this way.
Let´s see in a few days.
