VOLTAGE AND RESISTANCE PRODUCTS r 7 • 20 mQ to 23 MQ wide resistance range • 10 ms measurement time • 0.03% accuracy • 1 |jQ resolution • Automatic thermal and electromagnetic noise rejection • Programmable reference currents • GPIB, RS-232C and RS-422 compatibility (Model: 1740/GPIB) V_) Finally a resistance meter that doesn't force the choice between accuracy and speed. The 1740 milliohm resistance meter is based on TEGAM's industry proven microohmmeter platform for superior resistance measurement. Accuracy at high speed delivers more throughput with better yield. This improves your product quality and profitability. It's Fast The 1740 accelerates the high speed production line. In the Fast Mode the 1740 can set-up, zero-out thermal errors, acquire data and make its first reading in less than 12 milliseconds with an accuracy of up to 0.05%! Subsequent readings are provided every 10 milliseconds at a true rate of 100 readings per second! The 1740 provides speed and accuracy while automatically rejecting thermal and line noise. Patented circuitry eliminates thermal and electromagnetic measurement errors caused by contact between device handlers and the device-under-test. The 1740 rejects DC and AC noise offsets while maintaining its high speed test performance. It's High Powered The 1740's power is in the user's ability to quickly configure it through a selection of standard setup menus. With the 1740 you select your measurement mode, (Resistance, Ohms Comparator or Percentage Comparator), and measurement ranges, (from 20 mQ to 20 MQ). You have your choice of reference currents and triggering methods. You can also configure delay times, settling times and automatic thermal and noise rejection. If you don't need all this flexibility, just hit the AUTO RANGE button and enjoy the ride! It's Easy to Operate The 1740 is the state-of-the-art programmable ohmmeter that operates via front-panel or over the bus. Clearly labeled multifunction keys provide front panel control of range selection, reading modes, delays, triggers and measurement HOLD. Clear menu driven options provide easy setup for more sophisticated operation, too! The Front panel includes a manual TRIGGER and HOLD function and HI/GO/LO indicators for the open collector TTL output. It's Easy to Integrate The 1740 is unbelievably easy to program. The 1740/GPIB contains a full complement of interfaces including IEEE-488, RS-232C and RS-422. To maximize your programming efficiency, each of these interfaces is operated using the same programming command set and front panel indicators to provide continuous status of all operations. It's Easy to Calibrate Front panel calibration makes it easy to maintain the 1740 traceability right on the product floor and in less time than it takes to reload a resistor reel. It's Ready for Any Job The 1740 provides the speed and accuracy desired for automated production test requirements as well as bench top quality control and inspection applications. Not only is the 1740 perfect for high speed production test of low resistance electronic components, but the low current capability and "TRUE-SPEED" performance make the 1740 excellent for dry circuit testing of switches, relays and connector contacts without disturbing the device's contact surfaces. 1740 fits most resistor, wire, fuse, thermistor and trimmer testing applications.
