	To set the current limit, temporarily short the '''-''' and '''+''' terminals together with a piece of wire or (ideally) a banana plug patch cord. Make sure this conductor is large enough to safely carry the current you're dialing in. If necessary, raise the voltage limit until the supply is in CC mode, with the '''C.C.''' LED lit. Then, adjust the current knobs until the readout above them indicates the desired current.

			Note: There are three terminals on this supply, '''+''', '''-''' and '''GND'''. '''+''' and '''-''' are the positive and negative terminals between which supply current flows, and are the two terminals you normally use. '''GND''' is a direct connection to the ground prong on the wall outlet; you use this if the circuit you are powering requires a safety ground, or if you need '''-''' to be held at local ground voltage.

	To operate this supply, you set ''upper limits'' for both output voltage and output current. The supply initially tries to keep its output at the voltage limit, by allowing current to vary. This is called "constant voltage" (CV) operation~~, and the '''C.V.''' LED is lit when operating in this mode~~. If the current needed to ~~maintain~~ this ~~voltage~~ exceeds the current limit, then the supply operates in "constant current" (CC) mode instead~~, and the '''C.C.''' LED is lit instead of '''C.V.'''~~. In CC mode, current is held constant by allowing voltage to vary. This supply can therefore be ~~used as~~ either a constant voltage source ''or'' a constant current source! To provide constant voltage, set the current limit higher than the current your load will draw at the intended voltage.
