Line Description
40 to 52 Enables SMUs and performs the measurement. After that, checks if an error occurred.
If an error is detected, forces 0 V and goes to Check_err. Also reads the measured data
and displays it on the console window.
53 to 56 Applies 0 V from all channels, disables SMUs, and closes the connection with the
Keysight E5260/E5270.
58 to 62 Displays a message box to show an error message if the error is detected.
64 to 69 Reads the program lists stored in the internal program memory, and displays it on the
console window.
