Storage Nomenclature
This isn't a field recalibration procedure as is the
procedure in your instruction manual. This is a ;
guide in calibrating brand-new instruments, just
assembled instruments that have never been turned
on before. Therefore it calls out many procedures
and adjustments that are rarely required for sub-
sequent recalibration.

Even though we wrote this procedure primarily for ol tos 4 |
our own factory test department, it's valuable to April,
others also if used with some caution:
|
1. Special testequipment, if mentioned, is not Supersedes
available
from
Tektronix unless it's listed also in January 1963
' our current catalog. This special equipment is used
in our test department to speed calibration. Usually
you can either duplicate its function with standard For 564 and RM564,
equipment in your facility, devise alternate ap- all serial numbers,
proaches, or build the special test eqiipmient your -
self,
2. Factory circuit specifications are not guaranteed unless they also appear ascatalog —
or instruction manual specifications. Factory circuit specs usually are tighter than adver-
tised specs. This helps insure the instrument will meet or exceed advertised specs after
shipment and during subsequent field recalibrations over several years of use. Your
' instrument may not meet factory circuit specs but should meet catalog or instruction
manual specs.
as Presetting internal adjustments, if mentioned, usually is unnecessary. This is help-
ful for "first-time" calibration only. If internal adjustments are preset, you'll have to
perform a 100% recalibration. So don't preset them unless you're certain a "start-from-
scratch" policy is the best.
In this procedure, all front panel controls for the instrument under test are in capital
letters (SENSITIVITY) and internal adjustments are capitalized only (Gain Adj).
