02 | Keysight | 34401A Digital Multimeter - Data Sheet Measurement capability – 6½ digit resolution – 10 measurement functions: DC/AC voltage, DC/AC current, 2- and 4-wire resistance, diode, continuity, frequency, period – Basic accuracy: 0.0035% DC, 0.06% AC – 1000 V max voltage input, 3 A max current input System Capability – 1000 readings/second – 512 reading memory www.keysight.com/find/dmm Superior performance The Keysight Technologies, Inc. 34401A multimeter gives you the performance you need for fast, accurate bench and system testing. The 34401A provides a combination of resolution, accuracy and speed that rivals DMMs costing many times more. 6½ digits of resolution, 0.0015% basic 24-hr dcV accuracy and 1,000 readings/s direct to GPIB assure you of results that are accurate, fast, and repeatable. Use it on your benchtop The 34401A was designed with your bench needs in mind. Functions commonly associated with bench operation, like continuity and diode test, are built in. A Null feature allows you to remove lead resistance and other fixed offsets in your measurements. Other capabilities like min/max/avg readouts and direct dB and dBm measurements make checkout with the 34401A faster and easier. The 34401A gives you the ability to store up to 512 readings in internal memory. For troubleshooting, a reading hold feature lets you concentrate on placing your test leads without having to constantly glance at the display. Use it for systems testing For systems use, the 34401A gives you faster bus throughput than any other DMM in its class. The 34401A can send up to 1,000 readings/s directly across GPIB in user-friendly ASCII format. You also get both GPIB and RS-232 interfaces as standard features. Voltmeter Complete and External Trigger signals are provided so you can synchronize to other instruments in your test system. In addition, a TTL output indicates Pass/Fail results when limit testing is used. To ensure both forward and backward compatibility, the 34401A includes three command languages (SCPI, Keysight 3478A and Fluke8840A/42A), so you don’t have to rewrite your existing test software. An optional rack mount kit is available. Easy to use Commonly accessed attributes, such as functions, ranges, and resolution are selected with a single button press. Advanced features are available using menu functions that let you optimize the 34401A for your applications. The included Keysight IntuiLink software allows you to put your captured data to work easily, using PC applications such as Microsoft Excel or Word to analyze, interpret, display, print, and document the data you get from the 34401A. You can specify the meter setup and take a single reading or log data to the Excel spreadsheet in specified time intervals. Programmers can use ActiveX components to control the DMM using SCPI commands. To find out more about IntuiLink, visit www.keysight.com/find/intuilink 3-year warranty With your 34401A, you get full documentation, a high-quality test lead set, calibration certificate with test data, and a 3-year warranty, all for one low price.
