Set up the low-resistance application using SCPI commands
The following sequence of SCPI commands makes 100 low-resistance measurements by sourcing
current and measuring resistance. In this example, the source current magnitude and limit voltage are
set automatically. It uses remote commands to change the front-panel display to show the GRAPH
swipe screen. This allows you to view numeric data at the top of the screen and graphic data at the
bottom of the screen.
You may need to make changes so that this code will run in your programming environment.
