Redpitaya Forum

Hi,

I wanna know how to use the LCR meter.
My Redpitaya LCR meter can measure as low as 1nF, not 1pF. According to the specification, STEMlab 125-14 can measure 1pF. But I am unable. Is there a calibration method or other way to measure up to pF? And there is no select range option for pF. Is it possible to measure up to pF with the app?

Thanks,

Hello Fabian,

Sorry for the late response.

The resolution of the LCR meter is 1 pF. You can see that from the number of decimal places when you select the range of 1 nF. However, I would not recommend measuring such low values because it is in the lower limit range. Also, almost anything you measure will have a higher capacitance (even the wires).
