Maintenance
3.
If steps 1 and 2 do not remove all the dust or dirt, all modules in the
oscilloscope except the Display Module and Front Panel Module may be
spray washed using a solution of 75% isopropyl alcohol.
During cleaning of the Acquisition board (Main board), make sure that
no residue is left in the attenuators. Debris or residue can cause several
problems with signal
fi
delity that cannot be corrected by calibration.
When handling the board, avoid handling the attenuators since skin oils
may cause problems.
Extensive cleaning of the Display Module is dif
fi
cult because water must
not be trapped between the display shield and the display. The polarizers
integrated into the display degrade with long-term exposure to water. The
display shield and display must be replaced as an assembly if signi
fi
cant
moisture or debris become trapped inside. Cotton tipped applicators and
lint-free rags moistened in isopropyl alcohol and/or deionized water offer
the best cleaning with the least opportunity for damage to the assembly.
The Front-Panel module can be damaged by deposition of
fi
lm or debris
inside the knob encoders. To avoid this, be careful not to drip liquid or
blow debris into the encoders.
4.
Spray wash dirty parts with the 75% isopropyl alcohol solution and wait
60 seconds for the majority of the alcohol to evaporate.
5.
Use hot (49 °C to 60 °C / 120 °F to 140 °F) deionized water to thoroughly
rinse the parts.
6.
Dry all parts with low-pressure, deionized air.
7.
Dry all components and assemblies in an oven or drying compartment using
low-temperature (52 °C to 66 °C / 125 °F to 150 °F) circulating air.
Lubrication.
Periodic lubrication is not required for the oscilloscope.
