Cleaning Procedure

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.

 

 

 

 

 

 

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.

 

 

Do not allow excessive alcohol to run into the connector. Excessive alcohol entering

CAUTION

 

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.

WARNING

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.

 

 

 

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.
