Hello Mishra,
Unfortunately, that series of power supplies cannot be programmed to supply negative voltage. However, if you swap the leads, red lead plugged in to black/negative channel output, and the black lead plugged in to the red/positive channel output, you can supply a negative voltage through your DUT or Device Under Test.
