mode, follow these steps:
1. Turn the POWER off to the PS280 or PS283.
2. Connect the outputs as shown in Figure 6.
3. Set both variable supply VOLTAGE controls to the minimum
setting.
4. Set both variable supply CURRENT controls to midrange.
5. Turn on the POWER to the PS280 or PS283.
6. Set the desired voltages for both variable power supplies.
7. Turn the POWER off to the PS280 or PS283 again.
8. Connect the device or devices to be tested.
9. Turn on the POWER to the PS280 or PS283 again. If necessary,
readjust the voltages.
Figure 7 shows the configuration for three ground-referenced
negative power supplies.
