3. Turn the front panel AC power switch to ON.
After a short power-on delay, the front panel digital meters and the CV
annunciator illuminate. Both voltmeter and ammeter displays should read zero.
Check the front panel annunciators. If OUT ON is illuminated, press OUT ON/
OFF to disable the output. The OUT OFF annunciator should now be illuminated.
For an illustration of the annunciators and their locations, see “Status
Annunciators” on page 1–9.
If the ERR indicator is lit, see “Read Error Messages” on page 3–26 or page 4–35
on how to read an error message, and consult Appendix D to determine the
meaning of the error. If an unexpected error persists after the power has been
cycled, contact the manufacturer for assistance.
Voltage Mode Operation Check
To complete the voltage mode operation check:
1. Ensure that the OUT OFF annunciator is illuminated. If OUT ON is
illuminated, press OUT ON/OFF.
2. Connect a Digital Voltmeter (DVM) to the output terminals on the rear panel,
observing correct polarity.
3. Press OUT ON/OFF to turn the DC output ON.
4. Slowly turn the Current knob clockwise 1 or 2 turns. Slowly turn the Voltage
knob clockwise and observe both the front panel voltmeter and the DVM. Do
not exceed 10V.
5. Compare the DVM reading with the front panel voltmeter reading to verify
the accuracy of the internal voltmeter. Both readings should be the same
within the accuracy of the meters. The minimum control range is from zero to
the maximum rated output for the power supply model. Check that the
Constant Voltage (CV) annunciator is illuminated.
WARNING
On units rated higher than 40V, ensure that the electrical connections are
protected to prevent accidental contact.
CAUTION
When making connections to the bus bars, ensure that each terminal’s mounting
hardware and wiring assembly are placed so they don’t touch the other terminal
and short the power supply outlet. Heavy connecting cables must have some
form of strain relief so the connections aren’t loosened and the bus bars aren’t
bent.
