What I am trying to do is to control the power supply where I can control the voltage step at time intervals. My issue is that each time i run the VI the 2nd channel is not being used will give out a readoing of 1V and this 1V will affect the readings when i try to control both channels of the psu simultaneously which also will lead to constant change in the readings displayed on the psu. Why does this extra voltage appear when i run this VI. Is there anyway to eliminate it so that I may have full control of both the channels.
