O = Open termination
S = Short circuit termination
L = Non-reactive 50-ohm load termination

All applied to the source port.

You may also see "T" in an OSLT designation.

T = Through with the supplied coaxial cable between the source and sink
ports.

Correction?

Once you complete your chosen cal., go back and check that the OSL actually
shows as an OSL should. If so, that will assure your cal has taken hold.

Please excuse my 80yr old brain, I know to include the rest of the info.
but didn't type it.
I have a NanoVNA H4 with FW version 1.2.40.
My question is;
Is 1.2.40 the latest FW or is there a newer version?
The reason for my question is the "Calibration correction" does not show
on the menu selections on my version of FW.
Thank you in advance.
