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