Adjustment Procedures
This chapter contains the factory adjustment procedures for the oscilloscope.
Only qualified personnel should perform service procedures. Read this Service
Safety Summary and the General Safety Summary before performing any service
procedures. Also refer to the chapter Operating Information for information
about using the oscilloscope.
NOTE. The voltage references inside the oscilloscope are very stable over time
and should not require routine adjustment. Before performing any procedure in
this chapter, first verify that the oscilloscope does not meet specifications. Refer
to the chapter Performance Verification for procedures to verify the specifica-
tions.
