Interior Cleaning
1.
Blow off dust with dry, low-pressure, deionized air (approximately 9 psi).
2.
Remove any remaining dust with a lint-free cloth dampened in isopropyl
alcohol (75% solution) and rinsed with warm deionized water. (A
cotton-tipped applicator is useful for cleaning in narrow spaces and on circuit
boards.)
NOTE.
If, after performing steps 1 and 2, a module is clean upon inspection,
skip the following steps.
If there is still dust or dirt on the module, the oscilloscope may be spray washed
using a solution of 75% isopropyl alcohol by following these steps:
a.
Spray wash dirty parts with isopropyl alcohol and wait 60 seconds for the
majority of the alcohol to evaporate.
b.
Use hot (120 °F to 140 °F) deionized water to thoroughly rinse them.
c.
Dry all parts with low-pressure, deionized air.
d.
Dry all components and assemblies in an oven or drying compartment
using low-temperature (125 °F to 150 °F) circulating air.
Lubrication
There is no periodic lubrication required for this oscilloscope.
