List operation 
You can use lists to set up the instrument to source specific voltage and current values to a device 
under test (DUT). You can specify up to 99-step points of voltage and current limit. You can also 
specify a different dwell time for each step.   
When you run a list, the instrument uses the trigger model that contains the settings you selected for 
the list.   
To start a list, press HOME > List > Enable. You can also use an initiate command over the remote 
interface.
