GPIB & RS-232
The model 1740 high-speed microohmmeter has similar capabilities to the 1750 but limits the maximum output current to 100 mA, which protects sensitive test samples. Fuse manufacturers can use it for nondestructive tests where the unmatched precision increases the process yield to the point where the 1740 pays for itself in weeks. Resistors from 1 m Ohm to 20 M Ohm can be tested and sorted to accuracy better than 0.1% by the 1740. Automotive suppliers can use it to consistently meet the stringent quality requirements of welds, bonds and electrical connections in sub-assemblies. Battery manufacturers employ the 1740 to measure the integrity of interconnects between individual cells in large battery arrays. The capability of the 1740 microohmmeter enables the accurate real-time measurement of electro-plating thickness and conductive coatings on housings and shields.
TEGAM's 1740 microohmmeter employs multiple techniques to achieve its impressive accuracy. A four-wire kelvin technique eliminates the effects of lead resistance while offset compensation removes the errors caused by thermal contact voltages. The 1740 even monitors its performance over time and adjusts its calibration against a set of internal low temperature coefficient resistors to ensure consistent measurement performance without constant recalibration.
