National Instruments 778274-01 PXI Digital Multimeter
Part number 778274-01 from National Instruments is the identifying part number for the PXI-4070 PXI Digital Multimeter. Designed with both AC and DC systems, the versatile 778274-01 excels in providing test systems with high-resolution measurements and high-speed digitization.
The DC system of the 778274-01 boasts a range or function change speed of 100/s. It features auto range time capabilities, exhibiting an auto range time of 5 ms for both DC I and DC V. The auto range of the device encounters resistance of only 50 ms. The 778274-01 multimeter has an incredibly low trigger latency at only 2 μs in addition to a max trigger rate of 6 kHz.
The speed for range or function change with the AC system of the device is measured at 10/s, while the AC auto range time is 250 ms for both AC I and AC V. The trigger latency remains consistent with the DC system with a measurement of 2 μs, while it’s maximum trigger rate is significantly lower at 1 kHz.
The 778274-01 features an acquisition system with two available functions: voltage or current. The voltage function can be coupled with either DC or AC and ranges from ±100 mV to ±300 V, while the current function operates within a range of ±20 mA to ±1 A. The multimeter allows for peace of mind for the user with a reliable 25 ppm of timebase accuracy.
One of the standout features of the 778274-01 is its self-calibration abilities. The self-calibration process calibrates the FlexDMM relative to high-precision internal voltage and resistance standards, reducing the recommended external calibration interval to around every 2 years.
The dimensions of the 778274-01 measure 2.0 cm × 13.0 cm × 21.6 cm (0.8 in. × 5.1 in. × 8.5 in.), while the compact design weighs a mere 340 g (12 oz).
