To set the output to 20 V ac at 60 Hz, press:
2→ 0 → V → 6 → 0 → H→ E→ O
To change the output to dc, press:
0 → H→ E or I → E

4-22. Setting DC Voltage Output
Complete the following procedure to set a dc voltage output at the 5520A front panel
NORMAL terminals. If you make an entry error, press Gto 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
Calibrator to a UUT."
3. Set the UUT to measure dc voltage on the desired range.
4. Press the numeric keys and decimal point key to enter the desired voltage output
(maximum seven numeric keys). For example, 123.4567.
At voltage outputs of 100 volts and above (nominal), you may notice a
slight high-pitched sound. This is normal.
5. Press I to select the polarity of the voltage (default is +).
6. Press a multiplier key, if necessary. For example, press c.
7. Press V.
8. The Control Display now shows the amplitude of your entry. For example,
123.4567 mV (below).
