User’s Manual Sweep Operation 10-27
Sweep branching program example
The code fragment below is a Visual Basic sweep branching subroutine. This example sets
up source memory locations 1-3 as indicated in code comments. Location 100 is used as a
dummy location. Failure at any one of locations 1-3 causes a branch to location 100 to
stop the sweep as soon as possible in the event of failure. For all three source memory
locations, operating modes are set as follows:
• Source function: volts, 10V output voltage
• Measurement function: current, 100mA range, 105mA compliance
• Delay: 1s
Test limits for the three memory locations are:
• Location 1: 10mA to 20mA
• Location 2: 20mA to 30mA
• Location 3: 30mA to 40mA
