Maintenance
General Care
For best perfor
mance, follow these recommendations:
Protect the oscilloscope from adverse weather conditions. The oscilloscope is
not waterproo
f.
Do not store or leave the oscilloscope where the liquid crystal display (LCD)
is exposed t
o direct sunlight or high humidity for long periods of time.
The front and rear cases help keep dust out of the oscilloscope and must be in
place durin
g normal operation.
To avoid damage to the oscilloscope or probes, do not expose them to any
sprays, li
quids, or solvents.
Interior Cleaning
Use a dry, low-velocity stream of air to clean the interior of the chassis. Use a
soft-bristle, non-static-producing brush for cleaning around components. If you
must use
a liquid for minor interior cleaning, use a 75% isopropyl alcohol solution
and rinse with deionized water.
WARNING. To avoid injury, power off the instrument and disconnect it from line
voltage before performing any procedure that follows.
Exterior Cleaning
CAUT
ION. Avoid the use of chemical cleaning agents, which might damage the
plastics used in this oscilloscope. 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.
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.
D
o n ot use abrasive compounds on any part of the chassis that may damage the
chassis.
CAUTION. To prevent getting moisture inside the oscilloscope during external
cleaning, use only enough liquid to dampen the cloth or applicator.
Clean the On/Standby switch using a dampened cleaning towel. Do not spray or
wet the switch directly.
