In times when buttons and knobs as control elements are disappearing from the front panels of laboratory instruments, the DMM7510 offers a good compromise: The user interface is implemented as a 5" capacitive touchscreen with scroll-down function but some functions are duplicated as buttons on the front panel. As a concession to dyed-in-the-wool smartphone users, the top level of the user interface resembles a smartphone user interface; the functions appear much like an app.


With its 7 ½ bit resolution, the instrument provides a DC accuracy that typically is found in metrology-grade products but at a significant lower price of some € 3.300 (about 2.770 GPB in the UK). The DMM7510 offers high sensitivity, offering measurement ranges of 100 mV, 1 Ohm and 10 microamps. The instrument also offers support for low-resistance applications including dry circuit, offset compensations and open lead detection. Its capability to measure ultra-low resistances makes it the perfect suit for tasks that require contact resistance, says Keithley Technical Marketing Manager Peter Bachmayr.


The oscilloscope function focuses on quickly analysing current and voltage waveforms and transient without the need to employ a full-fledged oscilloscope. With an integrated 18-bit digitiser for waveform capture and display, the instrument offers a bandwidth of 1 Mbyte, the capability to capture 1 MSamples per second an a certain selection of trigger functions.


With features like front and rear inputs, a built-in test script processor and interfaces like GPIB, LXI and USB, the DMM7510 is also addressing applications in test automation and production test fields. For such applications, the instrument is also available in a version without display. A free software is available that enables users to control the instrument through a PC and to store and process the measurement data.
