To operate the DC Load in CW mode in a dynamic condition, see the Lists section.

Constant resistance mode

In constant resistance mode, the DC load will behave as a fixed resistance value. To set up the DC
Load
to operate in constant resistance mode and in the steady state condition, use the following
