FAQs

How should I clean the front-panel display?

If you need to clean the front-panel LCD touchscreen display, 

use a soft dry cloth. If necessary, use a cloth dampened with an 

ammonia-free glass cleaner. Do not spray cleaning 

fl

 uids onto the 

display. Additionally, it is strongly recommended that you use only 

fi

 ngers on the touchscreen. Do not use sharp objects, such as a 

pen or pencil, to touch the touchscreen.

My data looks odd or is wrong. What should I do?

Verify the connections from the instrument to the test 

fi

 xture. Also 

check the connections from the DUT to the test 

fi

 xture socket.

I cannot unplug the mini-triaxial cable (4200A-MTRX) from 
the SMU. What should I do?

The mini-triaxial connector is a locking connector. To remove it, 

pull the knurled part of the connector back.

A confi guration error has been detected and I cannot 
launch Clarius. What should I do?

This occurs when the physical con

fi

 guration does not 

match the con

fi

 guration de

fi

 ned in KCon or when there are 

communication problems between instruments and the 

4200A-SCS. 

To verify system confi guration:

1. Run 

KCon.

2. Select 

Validate Confi guration

This can also occur if the preampli

fi

 er, RPM, or CVIV is 

removed or reconnected. 

To update the system confi guration:

1. Run 

KCon.

2. Select 

Upgrade Preamp, RPM, and CVIV Confi guration

.

Note that preampli

fi

 ers are SMU speci

fi

 c. For example, a 

preampli

fi

 er that is con

fi

 gured for SMU1 cannot be connected 

to SMU2.
