The National Instruments PCI-4065 (Part Numbers: 779770-01, 190310C-01) is a professional-grade digital multimeter designed for precision measurement applications. This PCI-based instrument delivers exceptional accuracy and reliability for both analog-to-digital and digital-to-analog voltage measurements, current measurements, diode testing, and 2-wire or 4-wire resistance measurements.

• 6.5-digit resolution for high-precision measurements
• Voltage measurement range: ±300V (DC or RMS)
• Current measurement range: -3A to 3A
• Maximum sampling rate: 3 kS/s
• Basic DC voltage accuracy: 90 ppm
• PCI bus connector for easy system integration
• Supports NI-DMM driver and software for enhanced performance
• Compact design: 7.2 x 0.8 x 4.7 inches, 11.5 oz weight

Ideal for educational laboratories, OEM applications, and cost-conscious test and measurement environments. The PCI-4065 provides reliable performance for basic to intermediate precision measurement needs.

The device is supported by NI-DMM instrument driver and compatible with NI LabVIEW SignalExpress and NI-DMM/Switch Express VI. Regular software updates from National Instruments help maintain system stability and hardware performance.

The PCI-4065 should be calibrated annually, though frequency may vary based on application requirements. Calibration requires specific equipment including a multifunction calibrator, low thermal EMF connections, and copper cables.
