ESR test frequency

Why there is a 166kHz frequency on RA1, RA2 (IC2) output instead of 100 kHz as it was written in article?

The difference is due to programming of the control PIC. Although 166 kHz insted of 100 kHz will not seriously affect the absolute ESR value readings, in some cases it does complicate the calibration process as described.
A new version of the firmware (which also corrects other minor flaws of the instrument) is expected shortly.

I never get the same reading measuring one capacitor over and over again. I just rely on my first reading and suppose the cap is OK. I am going to donate it to somebdy after finishing the 500ppm LCR one.
