A variety of power supplies are available. Generally, their use is rather straightforward but some simple principles apply. Perhaps most important relates to ensuring that, for a multi-output power supply, the ground has been correctly established. Typical of lab power supplies are those providing a fixed 5 volt output (with associated ground connection) and a couple of variable (e.g. +/- 12 volts) output voltages. These variable output voltages may have their own associated ground connection. Often, this means that the variable voltage outputs are "floating" relative to the 5 volt output. Connect all the ground connections together to establish a common ground (0 volts) point. Otherwise, your "12 volt output" used with the ground associated 5 volt fixed output may be far from 12 volts, despite what the meter display says. Agilent's user's maual and discussion of basics for the Agilent E3620 power supply will provide the information you need.
