other indicators on the front panel will be on by turn. When the cooling fan is being
checked, a high speed wind noise can be heard.
After the self checks, the CV, V and A LED indicators are lit up displaying voltage and 0.0
current. To find out about the set CC current level, just turn the current control knob one
