Switch problems with the 87511 S-Parameters test set

i use the Agilent 4395 Network Analyser with the A gilent 87511 S-Parameters Test Set and i got mechanical switch problems once Calibration done.
I use the HP 85052C calibration kit, i entered the specific characteristic in the Network Analyser, but once the calibration is finished, the S-Parameter test Set doesn't stop switching to S11 to S22. i can read the warning message "continuous switching may cause damage to your device".
The Calibration seems good, so what can be the cause of this "no-stop switching", and how fix it?

thank you for your precious help
