Inspection and Cleaning
Inspection and cleaning are done as preventive maintenance. Preventive
maintenance, when done regularly, may prevent oscilloscope malfunction and
enhance its reliability.
Preventive maintenance consists of visually inspecting and cleaning the
oscilloscope, and using general care when operating it. How often you do
maintenance depends on the severity of the environment in which you use the
oscilloscope. A good time to perform preventive maintenance is just before
adjustment of the oscilloscope.
For optimum performance, follow these recommendations:
H Protect the oscilloscope from adverse weather conditions. The oscilloscope is
not waterproof.
H Do not store or leave the oscilloscope where the liquid crystal display (LCD)
will be exposed to direct sunlight or high humidity for long periods of time.
H The front and rear cases help keep dust out of the oscilloscope and must be in
place during normal operation.
H To avoid damage to the oscilloscope or probes, do not expose them to any
sprays, liquids, or solvents.
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 down the instrument and disconnect it from
line voltage before performing any procedure that follows.
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.
Clean the On/Standby switch using a dampened cleaning towel. Do not spray or
wet the switch directly.
