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.

If the current rise time that is determined by the slew rate and the current setting is longer
than the soft start time, the actual rise time will be longer than the soft start time. If you want
to raise the current according to the soft start time, increase the slew rate.

To set the soft start time (OFF, 100 µs, 200 µs, 500 µs, 1 ms, 2 ms, 5 ms, 10 ms, or 20 ms),
from the menu, select “1. Setup” > “1. Function” > “Soft Start.”
