| Why some brands don't do LCR meters? |

Matrix also seem to have some decent LCR meters. However, none of these meters address my needs AFAIK. |
| coromonadalix:
just a matter of building a test rig for the xformers wiring, controle them as the same time you control your lcr to poll measurements, once a day you do zero cal open and or closed with some small mcu like arduino relays etc ... anything is possible if you want to bin parts |
| Stray Electron:
My guess is that all of the added wiring associated with all of the additional DUT (Device Under Test) circuits with a scanner card for multiple DUTs would play hell with the accuracy of an LC meter. Resistance meters can compensate for added wiring by using a 4 wire Kelvin connection but I don't think that that is realistically possible on an LC meter when testing multiple DUTs. |

In general, to get the best results with an LCR, you need to limit anything between the meter and the DUT. Cables have to be compensated properly, etc. |

I would measure the inductance end to end, then connect a 1khz (for example) AC on one tap and measure the rms voltage on all the other taps. That is easy to multiplex, compared to what you have in mind. |
