OD1402 - Lesson 1/Learning Event 1
Preventive maintenance on the oscilloscope consists of periodic
inspection and cleaning procedures. Lubrication is not required on
this equipment. Cleaning should be accomplished carefully to
prevent damage. The oscilloscope should be cleaned at least once
monthly under normal operating conditions. Operations in dusty or
other severe conditions may require more frequent cleaning.
Accumulation of dirt in the oscilloscope can cause overheating and
component breakdown. Dirt on components acts as an insulating
blanket and prevents heat from escaping. Dirt and dust can also
provide a possible electrical path that could cause a circuit
failure or a severe shock to the operator. It is important to
clean the oscilloscope at regular intervals.
