National Instruments PXI-4071 Digital Multimeter

Features

• High - precision measurement: It can quickly and accurately measure voltage in the range of ±10nV to 1000V, current in the range of ±1pA to 3A, resistance from 10μΩ to 5GΩ, as well as frequency/period and diode measurements.

• High - speed digitization: In the high - voltage isolated digitizer mode, it can acquire DC waveforms in all voltage and current modes at a sampling rate of 1.8MS/s. The acquired waveforms can be analyzed in the time and frequency domains.

• Wide measurement range: It covers a signal range from picoamperes to kilovolts, with 8 DC measurement ranges and 6 AC measurement ranges. Using a solid - state circuit shunt configuration, it has a wide current measurement range and can measure voltages from very small values to high voltages.

• High common - mode isolation: It has ±500V DC/Vrms common - mode isolation, which can be used to measure signals with high common - mode voltages, such as differential waveforms in fuel cell stack testing.

• Flexible integration: It can be used in conjunction with PXI switches to form a multi - channel high - voltage data acquisition system. For example, it can be used with the 12 - channel, 600V multiplexer of PXI - 2584 to test fuel cells or battery packs, or with the 64 - channel, 300V multiplexer of PXI - 2527 to achieve low - voltage, high - precision measurements.

Application Cases

• Fuel cell testing: In combination with switch modules such as PXI - 2584, it can test fuel cells or battery packs under 500V DC/Vrms common - mode isolation conditions, accurately measuring parameters such as voltage and current to help researchers evaluate the performance and efficiency of fuel cells.

• R & D and production testing of electronic devices: During the R & D and production of electronic devices, it is used to measure the voltage, current, and resistance of various circuit modules with high precision to ensure that the product quality and performance meet the requirements. For example, it can measure the power supply voltage of chips, the current consumption in circuits, and the resistance value of resistive elements, helping engineers identify design flaws and production problems.

• Motor control system testing: It can be used for electrical appliances with motor control systems, such as air conditioners, washing machines, refrigerators, general - purpose inverters, industrial motor equipment, robots, and machine tools. It measures and analyzes the operating parameters of motors, such as winding resistance, operating current, and drive voltage, to optimize the performance of the motor control system and improve the efficiency and reliability of the motor.
