Environment

NI power supplies and SMUs are designed to operate in any PXI-compliant chassis at an ambient temperature between 0 ºC and 55 ºC and at a relative humidity up to 90%.

For best performance, observe the following recommendations:

• Keep the power supply or SMU clean and free from contaminants.
• Use a chassis that has a well-designed cooling system. All NI PXI chassis meet this requirement.

Note  To ensure that the power supply or SMU operates at peak performance within the PXI chassis, refer to PXI Chassis Recommendations.

Operating under high humidity (>90%) or dusty conditions may cause increased leakage between circuit components and can result in additional measurement errors.
