Limit test program
The program listing below performs a limits test as covered in Section 11. This program
sets up the following operating modes:
• Source and measure channel: channel 1
• Source voltage: 1V
• Source delay: 100ms
• Limit 3 upper value: 10mA
• Limit 3 lower value: 4mA
• Limit 4 upper value: 8mA
• Limit 4 lower value: 6mA
