4-28. Setting a Dual DC Voltage Output
Tie the terminals NORMAL LO and AUX LO together at the UUT or at the
5520A, via the "LO"s softkey selection "tied."
The calibrator produces a dual dc voltage output by sourcing one dc voltage on the
NORMAL outputs and a second on the AUX terminals. Complete the following
procedure to set a dual dc voltage output. If you make an entry error, press Gone or
more times to clear the display, then reenter the value.
Verify the applied voltage to the UUT does not exceed the
rating of the UUT insulation and the interconnecting wiring.
1. Press R to clear any output from the 5520A.
2. Connect the UUT as described earlier in this chapter under "Connecting the
