This mode is appropriate for capturing the inrush current of a load by
programming the voltage to a specified value and capturing the
voltage and current at that moment in time. A further refinement can
be made by specifying the voltage start phase angle in the PROGRAM
2 screen. If this field is changed from RANDOM to 90°, the inrush
current can be captured under worst case conditions. In this case, the
voltage should be programmed to 0 volt before triggering the
acquisition using the START field.

Note:

When using the SET VOLT trigger source, the output relay MUST be closed to generate a
trigger. If the output is open, the acquisition will be armed when the START [ENTER] key is
pressed but will wait for the trigger event. Closing the output relay will generate the trigger
event. If the output relay was already closed when the START [ENTER] key is pressed, the
trigger will occur immediately.
