It will flash when the output is
enabled.

It will flash when the output is
on.
Note: INDEP mode:+source & -source out put is
independent; Tracking Mode :+source & -source out
put will follow the +source setting.
Serial output
If the load is connected between the positive and negative
output terminals, the unit becomes a power
source which can supply twice as much voltage as the rated
output voltage.
