Performance Verification and
Alignment Procedures
Appendix G
G.1
INTRODUC"nON
This appendix consists
of
two parts: the performance verification and the alignment
procedures. Use the performance verification procedure to check
the Model395 against
its published specifications. Then,
if
needed, use the alignment procedure
to
make
adjustments to ensure the unit meets specifications.
