To prevent damage to electrical components from moisture during

Clean the exterior surfaces with a soft dry lint-free cloth, or a soft-bristle brush.
If any dirt remains, use a soft 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 cleaning compounds.
CAUTION.
Avoid getting moisture inside the instrument during exterior cleaning;
use just enough moisture to dampen the cloth or swab.
Use only deionized water when cleaning. Use a 75% isopropyl alcohol solution
as a cleanser and rinse with deionized or distilled water.
Do not use chemical cleaning agents; they may damage the chassis. Avoid
chemicals that contain benzene, toluene, xylene, acetone, or similar solvents.
Remove the module covers to access the inside of the benchtop controller or the
expansion module for inspection and cleaning. Refer to the
