I feel an LCR meter upgrade coming up... But I really need a new laptop first  >:(

Martin72:
My upgrade will take a while, but then I won't need another one:

I did the open/short after the patient 30 seconds of waiting. 😉

Here's a warm up time comparison. Open/short correction applied after the specified time. Note: it's a THT fixture, the resistor is a 1% CMF, but it was not in the same position for both tests.

For my needs in general, the 30s time is plenty accurate.

When does your calibration expire? 😉
