The National Instruments USB-4065 is a high-performance digital multimeter designed for diverse applications including OEMs and educational laboratories. Ideal for cost-sensitive testing environments, this device features a 6½-digit resolution and supports multiple measurement functions such as AC/DC voltage, AC/DC current, 2- or 4-wire resistance, and diode testing. Equipped with USB 2.0 connectivity, the USB-4065 is compatible with PXI, PCI, and PCI Express systems, ensuring versatile integration with existing test setups.

This multimeter can handle current measurements up to 3 A and offers isolation of ±300 VDC/Vrms, prioritizing safety and functionality. It operates with standard APIs for NI LabVIEW, LabWindows/CVI, and Microsoft programming languages, facilitating straightforward programming. For basic benchtop measurements, the NI-DMM Soft Front Panel offers an intuitive interface, while LabVIEW's DMM/Switch Express VI streamlines the creation of high-channel-count data-logging systems.

With a maximum sample rate of 3,000 readings per second, the USB-4065 provides optimal throughput by allowing users to balance speed with measurement resolution. Its accuracy is maintained through continuous calibration cycles, ensuring reliable performance even under demanding conditions. The device features rapid range or function changes at a rate of 10/s and less than 1 μs trigger latency, enhancing data capture with a maximum trigger rate of 2.5 kHz.

In addition, the USB-4065 includes auto range timings for resistance, voltage, and current measurements, as well as effective common-mode rejection ratio (CMRR) and overrange protection. Designed for robust operation, the unit functions within a temperature range of 0 °C to 45 °C and a relative humidity of 10% to 90%, with storage capabilities between -40 °C to 70 °C and 5% to 95% relative humidity. The streamlined dimensions of 7.0 in. × 4.1 in. × 1.3 in. and a weight of 9.9 oz. contribute to its portability, while a three-year warranty provides confidence in its durability.
