Why some brands don't do LCR meters?
pope:
After a bit more digging I found out that apparently such devices do exist and they're called "Automatic Transformer Testers" but they are rather expensive and almost impossible to find them in EU or in the West in general...
here's n example
Martin72:
You can buy a transformer tester from sourcetronic:

Wayne Kerr is a western brand that makes magnetics analyzers, but you may not like the price. You will probably need to provide your own switching between windings, though.

For logging TestController supports a few LCR meters and it is free.

Well, my requirements are rather simple but I don't know where to look for.
I make a lot of multi-tap audio transformers and inductors and I'm trying to find a way to measure their values (and ideally log them) without connecting and disconnecting all the time.
So, in the case of a multi-tap inductor, one end of the LCR would connect to the first pin of the coil and the scanner would connect to the remaining pins, if that makes sense...
Here's a similar set-up

You could build a computer controlled relay box and then do it from TestController. There is a project here https://lygte-info.dk/project/LogicOutputs%20UK.html for digital output that works with testController. Relace the optocopler with relays and you have a relay box. The project is nothing more than a Arduino driving the relays.
pope:
thank you guys.
Martin, that's a bit beyond my budget and quite frankly overkill for my needs but thank you very much indeed for the recommendation :-+
HKJ: I'm into analog electronics and last time I did something digital was when Arduino was first launched some 20 years ago :)
Having said that, I'm quite confident that I can find my way into making something like this. Thank you for the link? Looks very interesting.
So, if I'm not mistaken, all I need is to build the suggested arduino project and some LCR meter that is being supported by testController like the East Tester ones?
The idea is to automatically switch through the various pins, log the data and then I need to find a way to exprt the data into excel where the matching would be take place.
At least that's what I'm hoping for... ;D
