5 Preventive Maintenance
Cleaning Procedure
1 Blow particulate matter from connectors using an environmentally-safe aerosol such as
Aero-Duster. (This product is recommended by the United States Environmental
Protection Agency and contains tetrafluoroethane. You can order this aerosol from
Agilent (see
Table 5 ).)
2 Use alcohol and a lint-free cloth to wipe connector surfaces. Wet a small swab with a
small quantity of alcohol and clean the connector with the swab.
3 Allow the alcohol to evaporate off of the connector before making connections.
WA R N I N G
To prevent electrical shock, disconnect the module from mains before cleaning.
Use a dry cloth or one slightly dampened with water to clean the external case
parts. Do not attempt to clean internally.
C A U T I O N
Do not allow excessive alcohol to run into the connector. Excessive alcohol entering
the connector collects in pockets in the connector’s internal parts. The liquid will
cause random changes in the connector’s electrical performance. If excessive
alcohol gets into a connector, lay it aside to allow the alcohol to evaporate. This may
take up to three days. If you attach that connector to another device it can take
much longer for trapped alcohol to evaporate.

Cleaning connectors with alcohol should only be performed with the
instruments’ mains power cord disconnected, in a well ventilated area.
Connector cleaning should be accomplished with the minimum amount of
alcohol. Prior to connector reuse, be sure that all alcohol used has dried, and that
the area is free of fumes.
WA R N I N G
If flammable cleaning materials are used, the material should not be stored, or
left open in the area of the equipment. Adequate ventilation should be assured to
prevent the combustion of fumes, or vapors.
