Can't lower voltage on the U8002A

I am using the U8002A.  When the supply is not connected to my board, I can change the voltage freely throughout the entire voltage range.  However, when I connect it to my board and hit the Voltage/Current button so that the "V" on the display blinks, I cannot lower the voltage.  I can raise it fine, but not lower.  Any idea what is going on?
Thanks,
Sue
