Basic Power Supply Operation 2-3
Outputting voltage and current
The fundamental process to output voltage and current is to 1) set the output voltage and cur-
rent limit values, and 2) press the OPERATE key. The details of this process are discussed as
follows.
Setting output voltage and current limit
The output capabilities of the power supply are shown in Figure 2-2. Figure 2-2A shows the
output capabilities for the 5A and AUTO measurement ranges. Notice that when voltage is set
to more than 9V, the maximum current limit is 3A.
