Measurement Techniques

Test Setup
All tests are performed at the rear terminals of the supply as shown in Figure 2-1. Measure the dc voltage directly at
the +S and -S terminals. Set the Remote/Local switch to Remote and connect the output for remote sensing. Use
adequate wire gauge for the load leads.
