Part Number: 779770-01

The National Instruments 779770-01, known as the PCI-4065 Digital Multimeter Device, is a high-precision instrumentation solution tailored for a diverse range of applications in industrial and laboratory settings. This versatile digital multimeter offers a resolution of 6½ digits, with selectable reading rates from 0.6 to 10 samples per second (S/s) for frequencies between 50 to 60 Hz. With an RMS noise level of 0.06 to 0.25 mV in the 10 V range, the PCI-4065 ensures accurate measurements across its multiple functions, including DC and AC voltage, DC and AC current, and resistance measurements.

For voltage measurement, the device covers a DC range from 100 mV to 300 V with an accuracy of ±(15 ppm of reading + 7 ppm of range), and an AC range from 200 mV to 300 V, with a frequency range of 10 Hz to 100 kHz and an accuracy of up to 0.2%. It can measure DC current from 10 mA to 3 A with an accuracy of ±(50 ppm of reading + 100 ppm of range) and AC current from 10 mA to 3 A in the 10 Hz to 5 kHz range, maintaining an accuracy of 0.3%. The multimeter also supports 2-wire and 4-wire resistance measurements from 100 Ω to 100 MΩ, achieving an accuracy of ±(20 ppm of reading + 8 ppm of range).

Designed for environments where low noise and high performance are paramount, the PCI-4065 is capable of operating under a temperature range of 0 to 40 degrees Celsius with a relative humidity of 10% to 90%, non-condensing, and can be stored in temperatures ranging from -40 to 70 degrees Celsius at relative humidity levels of 5% to 95%. Featuring a pollution degree rating of 2, it is intended for indoor use and can be mounted at altitudes up to 2000 meters. The compact form factor of 18.3 cm × 2.0 cm × 12.0 cm (7.2 in. × 0.8 in. × 4.7 in.) and a weight of 325 g (11.5 oz) makes it easily integrable into various setups. The device operates with a power requirement of less than 3 Watts from the PCI motherboard, ensuring efficient energy consumption while delivering precise measurements.
