National Instruments 778270-01

The National Instruments part number 778270-01 designates the PXI-4072 PXI Digital Multimeter, a sophisticated instrument engineered for precision measurements in a compact format. This multimeter delivers 6.5 digits of resolution and integrates the capabilities of a digitizer and a high-resolution digital multimeter, making it suitable for an extensive range of testing applications. With a maximum sampling rate of 1.8 MS/s, the PXI-4072 excels in providing accurate voltage and current assessments for both AC and DC signals. It supports diode testing and boasts rapid response times, with a DC voltage range or function change speed of 100/s and an auto-range time of 5 ms for both DC voltage and current, while its auto-range resistance is rated at 50 ms. The multimeter features low trigger latency of just 2 μs and achieves a trigger rate of up to 6 kHz for DC measurements, although this decreases to 1 kHz for AC. Noteworthy functionalities of the PXI-4072 also include self-calibration, which ensures accuracy by utilizing high-precision internal voltage and resistance standards. The device dimensions are 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.), with a weight of 370 g (13 oz). This product is supplied with a three-year warranty, underscoring National Instruments' commitment to quality and reliability in industrial automation and control systems.
