Connect - and + from ch2 and ch3 and use that as the 0V point.

Also, did you set the output mode to "Series"?

You best use tracking mode for +/- voltage out so you can see the exact voltage. Series mode is likely the same but you'd have to divide the reading by two mentally.

Thanks for the input!
The "tracking" tracks voltage but not for current |O
So I put a shorting bar between ch2- and ch3+ and program the 2 chs with keypad under independent mode, now it serves as a +/- supply for some sensor :-+

Mod.:
It would be possible to turn on ch2 and ch3 simultaneously with remote command "OUTP ON,(@2,3)" per user's manual.

This thread mentions several service bulletins (e.g. http://literature.cdn.keysight.com/litweb/pdf/E36313A-01.pdf and http://literature.cdn.keysight.com/litweb/pdf/E36313A-02.pdf

These links are now dead, and I cannot seem to find the documents, even using archive.org. Would anyone care to post the originals?
