Use Smith Chart. If your marker is in the upper half, it's inductive. If below, it's capacitance.

Can you kindly explain the method you have used to measure inductance and
capacitance with NanoVNA?

Phil, Are you using Nano VNASaver software on your computer to connect to
the NanoVNA or are you trying to do it directly? First thing to remember
is, Calibrate at the connection you are using to check your inductors or
capacitors etc. So if you are using alligator clips to connect to your
parts, you need to use a 50 ohm resistor at that spot. Lead lengths need to
be as short as possible because the wire leads do affect your readings.
There are several jigs you can make to check various components. Let me say
I am not real experienced with using the NanoVNA but I have used mine to
check inductors to read the uH value on my VNA H4 with some success. I have
found using my L/C meter is much simpler. There may be someone out there
that has more experience with this than I but I will watch this thread and
try to help you if I can.

Hi Everyone, I'm new to the VNA and trying to measure both inductance and
capacitance but getting stupid results. Is there someone who has this
version
of the VNA could walk me through the setup and menu to do this please. I
have
checked and checked the various You Tube videos but I am not getting the
results I should. I should also mention I am 80 years old. Trying to
complete
my QMX low pass filters. Failing to get any answers is there someone who
would
care to correspond by email with me. Very frustrated. Thank you for
looking.
