A quick question about the Rigol DP832 power supply.

[Spork Schivago]

Hello,

I just ordered a Rigol DP832 power supply the other day.  It should be here tomorrow.  I was reading through the manual to try and get an idea of how to use it and I came across a warning I don't really understand.   I've just started learning how to design my own circuits and haven't gotten very far.   I fix computers for a living though and I'm sure I can find a use for this power supply in my repair work along with the circuits I'm building to learn how they all work.  Anyways, here's the part in the manual that I don't really follow:

Do Not Provide Power for the Active Load.
In order to avoid the anti-irrigation current which leads to the power control loop out
of control and damages the powered device, this power supply can only provide
power for the pure load without the current output function.

Could someone please explain to me what this means?  Thanks!

What page is that on?  I can't find it in my manual...

it means you MUST NOT pump power into the supply - the supply can only provide current, can't sink current. e.g. you must not connect a load which is powered from other source as well.

Battery is also current source.

ONLY if the voltage of the battery is higher than the rigol's output

I believe it is true with all power sources in this context.

Page III, at the very end.

Thank you guys!   I really appreciate the explanation.  I might of tried it one day if I was trying to get higher voltage or current than what the Rigol supplied.
