Like Siglent or Rigol for example? Not big enough market? I could really do with a LCR meter with scanner card and data logger software that doesn't cost a fortune :) |

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

It seems LCR meters are quite specialized, with some of the big manufacuters like Wayne-Kerr and IET not making other general test equipment like DMMs, function generators or scopes. So I guess the overlap in technology between LCR meters and other basic test instruments is quite limited. For a scanner, I would use an external multiplexer like those made by Keithley (7001) and HP/Agilent/Keysight. But performance might be a bit degraded, especially at higher frequencies. |

why dont aston martin do a van or why dont kfc do a turkey burger ?very similar to there main market but different enough not to fit in with there business model |

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 |
