Before operation, review the instrument and manual for safety
markings and instructions. You must follow these to ensure safe
operation and to maintain the instrument in safe condition.
A.2 Initial Inspection
Inspect the shipping container for damage. If there is damage to the
container or cushioning, keep them until you have checked the
contents of the shipment for completeness and verified the
instrument both mechanically and electrically.
The Function Test gives a procedure for checking the operation of
the instrument. If the contents are incomplete, mechanical damage
or defect is apparent, or if an instrument does not pass the operator’s
checks, notify the nearest Agilent Technologies office.
WARNING To avoid hazardous electrical shock, do not perform electrical tests
when there are signs of shipping damage to any portion of the outer
enclosure (covers, panels, etc.).
