4 Calibration, Verification, and Service
Before Returning the Unit
If the unit is inoperative, verify that the AC power is securely connected to the instrument, the mains
outlet is live, and the power switch is on. Before returning the unit, cycle power on the unit to run the
self-test as described above. Press [Error] to view errors in the error queue. Then report those errors to
Keysight Support and be sure that the instrument was calibrated within the last year.
Repackaging for Shipment
To ship the unit to Keysight for service or repair:
Attach a tag to the unit identifying the owner, model number, serial number, and required service.
Place the unit in its original container with appropriate packaging material.
Secure the container with strong tape or metal bands.
If the original shipping container is unavailable, use a container that will ensure at least 10 cm (4 in.) of
compressible packaging material around the entire instrument. Use static-free packaging materials.
Keysight suggests that you always insure shipments.
