| | Please note that there is a new procedure for using the Seebeck/cryostat equipment. Users need to log their time in a purple notebook (notebook is placed beside cryostat). Since no body wants to ruin another person's experiment, please log in and leave a note implying the system is in use. The details of the procedure can be found in the first page of the purple notebook. |

| | There are two versions of the Seebeck program located on the desktop. Version 8.0 uses the Keithley 195A to read the differential thermocouple voltage. Version 8.1 uses a Tektronix DM5120 to do this. You want to use 8.0 unless the 195A is not working. Version 8.2 automatically converts the differential thermocouple voltage to a temperature. Currently, it assumes RT (40 uV/K). |
