the analyzer. Additionally, the capacitive model parameters, CO, Cl, C2, and
can be mathematically derived from the physical dimensions and material of
each calibration standard or from its actual measured response.
You are using a connector type (TNC or BNC for example) which is not one
of the selections under the CAL KIT menu.
You are using a built-in connector type, but your standards (such as a short)
have different characteristics than the built-in kit uses when performing a
