Digital Multimeter Tests More Diodes Including LEDs
Agilent Technologies has unveiled the Truevolt Series digital multimeters. These DMMs offer several advantages over previous models. They help engineers see their measurement data in new ways, get actionable information faster, and document their results more easily. Exclusive Truevolt technology reduces extraneous factors such as noise, injected current and input bias current.
The Compared with the 34401A DMM, the new 34461A offers expanded current ranges from 100µA to 10A. Both the 34460A and 34461A have a temperature measurement function (RTD/PT100, thermistor) and expanded diode measurement capability to allow engineers to measure a larger full-scale voltage (5V) so they can test more diode types, such as LEDs.
Most DMMs show results on a low-resolution numeric display. These DMMs offer a 4.3in., high-resolution, colour display to view numerical readings, long-term trends (34461A only), measurement histograms and statistical information. They can also set display preferences and pull them up automatically the next time they start up the instrument.
Driverless easy file access USB file transfer provides simple USB connectivity between an Agilent Truevolt DMM and a PC, using the standard USB media transfer protocol. Engineers can drag and drop measurement data, instrument settings and screen images into PC applications without any additional software.
The Digital Multimeter Connectivity Utility software lets engineers control, capture and view the DMMs on their benches. With a single click they can transfer data to a PC via USB, GPIB, LAN or RS-232 (when used with older-generation DMMs).
