How can I start a SSST calibration?

Question:

I have a calibration kit which consists of 3 offset short and one through standard

The calibration typ is called SSST

I can not find that type on ZVA/ZNB. Which type do I have to sele

At create a new calibration kit with the data of the standards.

Most important is that each offset short has a different length.

Then select TOSM calibration - that calbration kit will be accepted

The calibration can be performed without open and match standard.
