Stanford Research SR715 LCR Meter Teardown

here's the firmware for a SR720 v 1.03

will probably not work on a 715 though

I just noticed my SR720 is behaving weirdly for components with a high Q factor, for MKP capacitor the D factor always goes above 0.004 and the Q factor just jumps from 800 to 1200 randomly. The reading can only be stabilised unless I set the frequency to 10KHz, but still not in the range for what it is supposed to be.

It makes me start worrying about the testing I used to do for inductors and coils in the past few years
