How do you get a 30V output from the HP E3631A power supply?

Here's a diagram of the supply: http://www.ese.upenn.edu/rca/instruments/HPpower/psfig4.gif All I know is that you have to connect the voltage outputs at the bottom in series. What exactly gets connected to what? How about setting the voltage on the 6V side to 5V, and then connecting the positive terminal from the 6V side to the common ground on the 25V side, and connecting the + terminal on the 25V side to the - terminal on the 6V side?

1. connect the plus 6 side to the negative 25 side and take the output from the positive 25 to the negative of the 6 side. You will have 31V but a series diode, like a 1n4001 would give you about 30.3 volts when you are done.
2. you have two 0 to ±25 volts supplies. That means that between the ends, you have from 0 to 50 volts. So connect between the terminals marked ±25 volts, and you will be able to adjust the total between 0 and 50 volts, negative on the right red terminal and positive on the left red terminal. .
