Lower Display mV Source Tests

1. Press M on the UUT until SOURCE appears on the lower display; then press V
2. Set the HP 3458A to measure dc voltage in the 200 mV range.
3. Connect the UUT to the HP 3458A as shown in Figure 7.
4. Use the arrow keys on the UUT to set the UUT output to the current values in Table
5. Press Mon the UUT to disable the sourcing function.
