Cleaning the PXIe-4135 System

NI recommends the following to clean and maintain your SMU system:

• Clean the fan filters on the chassis regularly to prevent fan blockage and to ensure efficient air circulation. Cleaning frequency depends on the amount of use and the operating environment. For specific information about cleaning procedures and other recommended maintenance, refer to the chassis user documentation.
• Clean the hardware with a soft, nonmetallic brush. Make sure that the hardware is completely dry and free from contaminants before returning it to service.
• Due to high-impedance circuits used in the hardware, care should be taken to avoid contamination during handling or operation. Avoid use or storage of the hardware in an environment that allows dust to settle on the hardware. Avoid direct contact with the inner surfaces of triax connections. Triax covers should be used whenever triax connections are not in use.
