PCI digital multimeter card
max. 250 V, 2.5 A DCSM204x Series Geotest - Marvin Test Systems

The SM2040 provides a combination of resolution, accuracy and speed that surpasses rivals. A 6-½ digit display, 0.006% basic DCV accuracy and 1,000 rps assure you of measurements that are accurate, fast and repeatable. The SM2042 adds a comprehensive repertoire of measurements, and the SM2044 adds more measurements and source functions, packed into a half-size PCI plug-in module. Both measurements and sourcing functions are isolated from the PC and are therefore truly differential. An on-board controller responds to high level commands from the PC, minimizing overhead.The SM2040 series is designed as a universal, multifunction DMM. Measurements commonly associated with "high-end" system DMMs are standard features with the SM2040 family. Functions include 2-wire, 4-wire and 6-wire guarded resistance measurements, inductance and capacitance, leakage and temperature, RMS and peak-to-peak, frequency and timing, sourcing of voltage and current, and much more. The SM2044 is best suited for applications demanding precision sources with simultaneous measurements such as in Parametric testing, while the SM2040 is best suited where basic DMM functions are required.
The SM2040 series' unique "Relative" function allows you to remove lead resistance or other fixed offsets in your measurement and to perform percent deviation and dB measurements. An external, level controlled trigger can be used for capturing single-shot events, and can store up to 64 measurements on-board.
