I have modified the original file to include that meter, which I have attached, please try it.
If it works then the new file can be used instead.
Thanks Defpom,
I have tried your new "East Tester ET4xxx.txt" config file with my LCR meter.
With the new config file my RuoShui 4090C LCR Meter is indeed recognized, and I have verified that I can control the LCR meter with the Mode and Setup windows.
This is illustrated in attached screenshot at the end of this post.
I have a problem however with displaying the readout values (capacitance value and ESR value).
When I select Popups => Readout, the popup windows only shows four dashes ( ---- )
When I select Popups => Grid Panel, the popup windows shows 888888, and nothing is shown after "Select Channel".
I also did not manage to display readout values on tabs "Current values" or Table.
I have only just started to use TestController, so probably I am missing something.
When I start TestController in
debug mode, I can see that the values of Cs and ESR are actually read by TestController. The debug window shows the following information:

Unknown mode: 2.14122e-07
Known modes: ECAP, C, L, Z, R, DCR, ESR, D, X, Q, Deg, AUTO,
Note the line:
;; 90C: Rx <2.14122e-07,0.107718>
2.14122e-07 is the capacitor value, and 0.107718 is the ESR value. These are the exact values that are shown on the screen of the LCR meter.
But as said before, so far I did not manage to display these value on a popup window on my PC.
Also note the next line:
Unknown mode: 2.14122e-07
It seems that TestController expects a mode when reading the capacitance value?
Hints on how to display the capacitance value + ESR value are welcome!
