OUTPUT VOLTAGES AND CURRENTS
These are nominal voltages. They are the +20V and -20V
outputs of the HP 30310A Power Supply. The actual voltage
value is controlled by a signal from the HP 30311A Power
Supply as a function of load and temperature. The ±20V ADJ
potentiometer on the HP 30310A Power Supply must be set
fully clockwise.
