You are correct and I confirmed on the big box, that is the function performed.
This turns CAL ON or OFF. Again, I suspect hp as well others, added this function as an aid to be sure the correction data sets make sense as a corrective measurement is conducted on a component. Its much easier to do this then preset the instrument and have to do a complete re calibration.

Good suggestion and it does appear to toggle in that manner. Now, I have to think why I would toggle corrections ON and OFF, other than to see if the corrections ON make sense. I am not sure this is a good place to bring up the fact that the STANDARDS provided with the nanoVNA are taken, I believe, by the device and the firmware as IDEAL. Point in fact, they are NOT. Not an issue at lower frequencies unless you want to split hairs. But as you approach 900 MHz, bottom line, when measuring a component, you are not going to get the correct answer. I emailed the developer on this topic but as of now, no response.

I would guess it is a mode switch between: 'Apply calibration corrections' and 'Don't apply calibration corrections' This feature is present in other VNA's. Am not in front of a device to confirm it though. Regards, Roger On Mon, 29 Jul 2019 at 13:06, alan victor <avictor73@...> wrote: Good question Ernst.
