National Instruments 778270-01 PXI Digital Multimeter

National Instruments part number 778270-01 is the identifying part number for the PXI-4072 PXI Digital Multimeter. Boasting 6.5 digits of resolution, this versatile multimeter combines the features of both a digitizer and a high-resolution DMM into one powerful device. The high-performance 778270-01 provides the user with accurate voltage and current measurements for both AC and DC, making it the perfect choice for a variety of testing setups. The device is also equipped for diode testing, and can capture waveforms at a speed of up to 1.8 MS/s in the sample rate.

The DC voltage capabilities of the 778270-01 include an impressive range or function change speed of 100/s, as well as auto-range time of 5 ms for both DC voltage and DC current. The auto range resistance of the device has a speed of 50 ms. The trigger latency for the multimeter is low, measuring in at just 2 μs. When it comes to the trigger rate, the 778270-01 achieves a maximum of 6 kHz. 

The AC voltage of the 778270-01 has a lower range or function change speed of 10/s, but it features much higher auto-range times of 250 ms for both AC voltage and AC current. The trigger latency is the same as DC voltage specifications at 2 μs, while the trigger rate has a lower maximum value at just 1 kHz.

One of the more notable features of the 778270-01 multimeter is its self-calibration, which allows it to calibrate the FlexDMM relative to high-precision internal voltage and resistance standards. The device measures 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.) and has a nominal weight of 370 g (13 oz).
