I just purchased a Siglent SPD3303X-E bench power supply. It has three outputs, one of them being a range of fixed voltages, the other two being fully adjustable.

What I need is to be able to get +12, -12 and 0 volts from the unit. Would I do this by setting the outputs to independent mode, set both to 12 volts, then combining the inner + and - terminals to get my zero volt, using the remaining terminals for the + and - voltages?
