Figure 5-12: Current limit
CC mode
The current I
max
corresponds to the current setting adjustable in the instrument.
If I
out
reaches I
max
, the instrument switches to CC mode, i.e. the output current remains
constant and limited to I
max
even if the load increases. Instead, the output voltage V
out
decreases below V
set
. In a short circuit, the output voltage drops towards zero. In CC
mode, the font text in the channel display area changes to red.
