Operating Basics
Wiring in Parallel
By wiring Channel 1 and Channel 2 in parallel, you can use your power supply to provide up to 3 A to a device under test.
The following figure shows how to wire the outputs for Parallel operation. (See Figure 4.)
Your instrument can also be configured to read the combined current from two channels. See Combine metering of Channel
1 and Channel 2 when outputs are wired in parallel to learn how to set the instrument to measure the combined current.
(See page 18.)
Figure 4: Parallel setup for model 2230-30-1 and device under test. Parallel setup for model 2220-30-1 is the
same, but Channel 2 is on the far right.
Wiring for Bipolar Applications
The outputs of your instrument can be wired as a bipolar source. When testing a system in which independent positive and
negative supplies are needed, the outputs should be wired as shown here. (See Figure 5.)
To make the positive and negative supplies track together, you can activate tracking. See Use Tracking to learn more about
tracking and find out how to turn tracking on. (See page 18.)

but Channel 2 is on the far right.
