DTest Record

Results of the performance test may be tabulated on the Test Record provided at the end of the test procedures. It is recommended that you ￿ll out the Test Record and refer to it while doing the test. Since the test limits and setup information are printed on the Test Record for easy reference, the record can also be used as an abbreviated test procedure (if you are already familiar with the test procedures). The Test Record can also be used as a permanent record and may be reproduced without written permission from Hewlett-Packard.

Test Failure

If the HP81531A fails any performance test, return the instrument to the nearest Hewlett-Packard Sales/Service O￿ce for repair.

Instrument Speci￿cation

Speci￿cations are the performance characteristics of the instrument which are certi￿ed. These speci￿cations, listed in Appendix C, are the performance standards or limits against which the HP 81531A can be tested. Appendix C also lists some supplemental characteristics of the HP 81531A. Supplemental characteristics should be considered as additional information.

Any changes in the speci￿cations due to manufacturing changes, design, or traceability to the National Institute of Standards and Technology (NIST), will be covered in a manual change supplement, or revised manual. Such speci￿cations supercede any that were previously published.
