Series 1880 Milliohmmeter USES: Low Resistance Meter • Production Testing for Contact Introduction Resistance of Switches, Relays, The 1880 Milliohmmeter provides ease of use, digital display and excellent accuracy for Connectors, Cables, Printed performing low resistance measurements on switches, relays, connectors and a variety Circuit Boards and Other of other devices. The instrument offers a wide measurement range, from 1 µohm to Low Resistance Devices 2 Mohms, with constant current ranging from 1 A to 1 µA. A built-in comparator makes • Component Testing of Resistors, the unit ideal for go/nogo testing in a production environment and is also adaptable Motors, Fuses, Squibs and for use in automated system applications with it’s optional IEEE-488 interface. Heating Elements Description • Incoming Inspection and Quality Precision Measurements The 0.05% accuracy of the 1880 makes for consistent, Assurance Testing reliable test results from this economically priced unit. Nine measurement ranges, automatic or manually selectable, provide wide coverage between 2 Mohms and 1 µohm • Conductivity Evaluations in Product with constant current between 1 µA and 1 A. Design Easy to Use The 1880’s auto ranging and digital display means the instrument is ready to begin measuring on power-up, just connect the test device and meaningful results FEATURES: are immediately shown. • Measurement Range, 1 µohm to 2 Automatic Zeroing The device under test (DUT) is connected to the instrument Mohm front panel via a four-terminal Kelvin connection. This, along with the auto zero function •1 µA to 1 A, Constant Current for removing any stray resistance, renders very accurate low resistance measurements, independent of the test leads being used. • 0.05% Measurement Accuracy • Measurement Speed of 5/second Go/NoGo Testing A built-in thumb wheel comparator for setting high and low limits provides for fast, simplified, pass/fail testing in a high volume production environment. A • Easy to Read Digital Display nominal value can also be set by the operator, where test results are shown as a positive • Four-Terminal Kelvin Connections or negative percent deviation around this value. • Automatic Zeroing Automated Testing For automated system applications, the instrument includes an • Built-in Comparator for Go/NoGo I/O interface connection with remote start and pass/fail outputs. An optional IEEE-488 Testing interface is also available (or added later), which enables the 1880 to be used under computer control. • Display of % Deviation from Nominal • Auto Ranging For more detailed specifications, visit • Remote Control Interface www.quadtech.com • Optional IEEE-488 Interface For more information about special purchase, rent & lease options, call 1-800-253-1230 Fax 1-978-461-4295 Intl. 1-978-461-2100 HIPOT • LCR METERS • MEGOHMMETERS • MILLIOHMMETERS • DECADES • STANDARDS Product Specifications 1880 Milliohmmeter Resistance Range: Range F.S.
