•Be careful not to let the alcohol get on the insulator bead, as this may damage the bead.

•Be careful not to exert too much force on the center conductors, as they may be damaged.

•Compressed air can reduce the temperature of connectors dramatically, and this can have a significant effect upon the performance of calibration and verification components.

•If the connector components being cleaned are to be used in a critical measurement application, allow the temperature of these components to stabilize prior to use.
