4. Plug one of the test leads into the positive output terminal.
5. Plug the other test lead into the negative output terminal.
6. Press POWER to turn off the PS280 or PS283.
7. Clip the positive test lead to the positive pole of your device.
8. Clip the negative test lead to the negative pole of your device.
9. Press POWER to turn on the PS280 or PS283.
10. Push the AMPS/VOLTS selection switch so that the LED display
shows either voltage or current, as you want.
11. Rotate the VOLTAGE knob as desired.
12. If you are using a preset current limit (see page 10), do not touch
the CURRENT knobs. Otherwise, rotate the CURRENT knob as
desired.
Ground-Referenced. In the independently ground-referenced mode,
each variable power supply provides from 0 to 30 V referenced with
respect to ground at 0 to 2 A (0 to 1 A for the PS283). Any one of a
pair of output terminals, either the positive or the negative, can be
connected to ground. The FIXED 5 V power supply can also be
ground-referenced.
WARNING. In order to avoid grounding the power line, which can
cause electrical shock, explosion, or fire, isolate the device being
powered from the line voltage power source when using any
ground-referenced output configuration from the PS280 or PS283.
Figure 5 shows an example of a circuit with the FIXED 5 V terminal
referenced to ground and both the master and slave variable power
supplies referenced to –5 V.
