The extremely accurate measurement of resistance values in a variety of electrical manufacturing, electronic component testing and equipment calibration applications is provided by the Cropico DO5000 series of microhmmeters from Seaward. The versatile DO5000 has programmable current settings in 100 steps from 10uA to 10A and measures from 3mΩ to 30kΩ with a resolution of 0.1 μΩ and ±0.03% accuracy. Variable measurement speed settings of 50, 25 or 2.5 per second allows the selection of high speed testing for production line applications, a medium mode where the device under test needs more time to settle or a slow speed for manual operation where display clarity is a priority. True four-wire resistance measurement eliminates lead resistance errors, while auto averaging and automatic temperature compensation with 20°C referencing or other user-defined settings increases true measurement accuracy.
