Repackaging
If the instrument is to be shipped to a Tektronix Service Center for service or
repair, attach a tag to the instrument showing:
1. Owner (with complete address) and the name of the person at your firm that
can be contacted.
2. Instrument serial number and a description of the service required.
Repackage the instrument in the original manner for maximum protection. If the
original packaging materials are not in good condition or are unavailable, use the
following procedure to repackage the instrument. See Figure 6-8.
1. Obtain a corrugated cardboard carton whose inside dimensions are at least
six inches greater than the dimensions of the instrument to allow room for
cushioning. The shipping carton should have a test strength of at least
275 pounds.
2. Surround the instrument with polyethylene sheeting to protect the finish.
3. Cushion the instrument on all sides by tightly packing dunnage or urethane
foam between the carton and the instrument. Allow three inches on all sides
for cushioning.
4. Seal the carton with shipping tape or an industrial stapler.
