Inspection and Cleaning
Inspection and Cleaning
describes how to inspect for dirt and damage. It also
describes how to clean the exterior and interior of the waveform monitor.
Inspection and cleaning are done as preventive maintenance. Preventive
maintenance, when done regularly, may prevent waveform monitor malfunction
and enhance its reliability.
Preventive maintenance consists of visually inspecting and cleaning the
waveform monitor and using general care when operating it.
How often maintenance should be performed depends on the severity of the
environment in which the waveform monitor is used. A proper time to perform
preventive maintenance is just before any waveform monitor adjustment.
The cabinet helps keep dust out of the waveform monitor and should normally
be in place when operating the waveform monitor.
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.
Before performing any procedure that follows, power down the
instrument and disconnect it from line voltage.
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 instrument that
may damaged by it.
