SECTION 4
MAINTENANCE
CAUTION--VOLTAGES HIGH ENOUGH TO BE DANGEROUS ARE
PRESENT IN THIS INSTRUMENT. SINCE MUCH MAINTENANCE
MUST OF NECESSITY BE DONE WITH THE CASE REMOVED,
GREAT CARE SHOULD BE TAKEN. USE ONLY INSULATED
TOOLS, STAND ON A DRY FLOOR, AND IF POSSIBLE KEEP
ONE HAND IN YOUR POCKET.
REPLACEMENT OF COMPONENTS
Most of the components used in the construction of TEKTRONIX instruments
are standard parts obtainable from any well-equipped parts distributor. Some of
the components carrying 1% and 2% tolerances may not be so readily obtainable
but may be purchased from the manufacturer at these tolerances. The remainder
of the low-tolerance components are standard 10%- and 20%-tolerance parts that
are checked at the factory for proper value or performance. Replacement parts
are available on order from the factory at current net prices but in the case of
standard parts, it is probably more economical of time to purchase them locally.
It is not feasible to attempt to check out low-tolerance parts or matched pairs
without a reasonably large stock to choose from as the rejection percentage is
quite high in most cases.
This manual has been prepared to cover TEKTRONIX Type 511 Oscilloscopes of
all serial number ranges. Diagrams, parts lists and text have been expanded to
incorporate all instrument modifications adopted during the course of manufacture.
The serial ranges of instruments to which modifications were applied before shipping
from the factory have been noted wherever necessary.
However, because many instruments have been modified in the field and out of
serial sequence, component values and circuitry of a given instrument may differ
considerably from those indicated in this manual for its serial number. In some
cases, circuits were hand-tailored during the original factory calibration and test
procedure. You will find that this manual has been hand-corrected, if necessary, to
show these changes according to factory records.
To assure that you will receive correct replacement parts with the minimum
delay, therefore, it is important that you include a full descripton of the part and
its appropriate 6-digit TEKTRONIX Part Number as well as the circuit number,
instrument type and instrument serial number when you order.
Equivalent parts, supplied by the factory when the exact replacement parts
ordered are not available, will be accompanied by an explanation and will be directly
interchangeable in most cases.
