Returning an Instrument
If your instrument fails during the warranty period, Agilent
Technologies will replace or repair it free of charge. After your
warranty expires, Agilent Technologies will replace or repair it at a
competitive price. The standard repair process is “whole unit
exchange”. The replacement units are fully refurbished and are
shipped with new calibration certificates.
Contact your nearest Agilent Technologies Service Center. They will
arrange to have your instrument repaired or replaced.
Operating Checklist
Before returning your instrument to Agilent Technologies for service
or repair, check the following items:
Is the instrument inoperative?
Verify that the ac power cord is connected to the instrument.
Verify that the front-panel On/Standby switch has been pushed.
Is the display working?
If the display is hard to read, but front-panel LED is lit and the
fans are working, the display contrast setting may be too light or
too dark. Use the front panel menu to set the display contrast.
Does the instrument fail self-test?
Remove all external connections to the instrument.
Check that modules are installed next to each other, starting with
slot 1. If there are any empty slots (or filler modules) between the
power modules, the power system will not operate.
Check that the mainframe has the latest firmware installed.
Turn off the unit and cycle power to run self-test again.
Repackaging for Shipment
If the unit is to be shipped to Agilent Technologies for service or
repair, be sure to:
Attach a tag to the unit identifying the owner and indicating the
required service or repair. Include the model and serial number.
Place the unit in its original container with the appropriate
packaging material and secure the container with strong tape or
metal bands.
If the original shipping container is not available, place your unit in a
container that will ensure at least 4 inches of compressible packaging
material around all sides for the instrument. Use static-free
packaging materials to avoid additional damage to your unit.
Agilent Technologies suggests that you always insure shipments.
