The National Instruments PCI-4065 is a Digital Multimeter (DMM) designed for precise measurements in various applications, featuring a resolution of 6.5 digits. This versatile instrument is capable of measuring both analog-to-digital and digital-to-analog voltages and currents, along with conducting diode tests. With a maximum sampling rate of 3 kS/s and a basic DC voltage accuracy of 90 ppm, the PCI-4065 is ideally suited for educational laboratories and original equipment manufacturers (OEMs), as well as cost-sensitive testing environments. It supports 2 or 4-wire resistance measurements and provides voltage measurements within a range of ±300 V, applicable to both DC and RMS.

Calibration of the PCI-4065 is recommended annually, although the frequency may vary based on specific user requirements and applications. Calibration involves the use of appropriate equipment such as a chassis and multifunction calibrator, along with specialized low thermal electromotive force cabling and connectors. The DMM is powered by the NI-DMM driver, which is continually updated by National Instruments to enhance performance and reliability. Users can easily interact with the PCI-4065 through various software interfaces, including NI LabVIEW SignalExpress and DMM/Switch Express VI, with example programs available to demonstrate its functionality.

Weighing 11.5 oz and measuring 7.2 x 0.8 x 4.7 inches, the PCI-4065 operates effectively within a temperature range of 0 to 40 °C for use and -40 °C to 70 °C for storage. The product is supported by a three-year warranty and additional technical documentation is available for download. For pricing and further information, please contact a sales representative.
