Inspection and Cleaning
Inspection and Cleaning describes how to inspect for dirt and damage. It also
describes how to clean the exterior of the instrument. Inspection and cleaning are
done as preventive maintenance. Preventive maintenance, when done regularly,
may prevent instrument malfunction and enhance its reliability.
Preventive maintenance consists of visually inspecting and cleaning the
instrument and using general care when operating it.
The cabinet helps keep dust out of the instrument and should be in place when
operating the instrument.
Always keep the connectors on the instrument and optical cables covered with
the protective caps when not in use. Treat optical connections the same as you
would a camera lens or other precision optical gear.
Clean the exterior surfaces of the chassis with a dry, lint-free cloth or a soft-
bristle brush. If any dirt remains, use a cloth or swab dipped in a 75% isopropyl
alcohol solution. Use a swab to clean narrow spaces around controls and
connectors. Do not use abrasive compounds on any part of the chassis that may
damage the chassis. Do not attempt to clean the interior of the instrument.
Clean the On/Off switch using a dampened cleaning towel. Do not spray or wet
the switch directly.
CAUTION. Avoid the use of chemical cleaning agents which might damage the
plastics used in this instrument. Use only deionized water when cleaning the
menu buttons or front-panel buttons. Use a 75% isopropyl alcohol solution as a
cleaner and rinse with deionized water. Before using any other type of cleaner,
consult your Tektronix Service Center or representative.
