General Information
To inspect the probe
To inspect the probe
❏Inspect the shipping container for damage.
Keep a damaged shipping container or cushioning material until the contents of
the shipment have been checked for completeness and the instrument has been
checked mechanically and electrically.
❏Check the accessories.
Accessories supplied with the instrument are listed in "Accessories Supplied" in
table 1-1 later in this chapter.
• If the contents are incomplete or damaged notify your Agilent Technologies
Sales Office.
❏Inspect the probe.
• If there is mechanical damage or defect, or if the probe does not operate
properly or pass calibration tests, notify your Agilent Technologies Sales
Office.
• If the shipping container is damaged, or the cushioning materials show signs
of stress, notify the carrier as well as your Agilent Technologies Sales Office.
Keep the shipping materials for the carrier’s inspection. The Agilent
Technologies Office will arrange for repair or replacement at Agilent
Technologies’ option without waiting for claim settlement.
