Soft Start
You can use the soft start function to raise the input current gradually. The soft start function is
valid in constant current mode (CC mode). Soft start is useful when:
• The load is turned on at the same time that voltage is applied to the load input terminals.
• When the load is on and voltage is applied to it after a period of no input (0 V).
You can reduce the amount of output voltage distortion that occurs when the DUT starts by
setting an appropriate soft start time.
To set the soft start time (1 ms, 2 ms, 5 ms, 10 ms, 20 ms, 50 ms, 100 ms, or 200 ms), from
the menu, select “1. Setup” > “1. Function” > “Soft Start.”
