Miniature Benchtop DC Resistance Meter Low Parallel Resistance Tester Ultra Low Resistance Gauge Testing Instrument with Accuracy 0.02% Range 0.1μΩ to 1.2GΩ Handler RS-232 Interface

QIUSUO Miniature Benchtop DC Resistance Meter Low Parallel Resistance Tester Ultra Low Resistance Gauge Testing Instrument with Accuracy 0.02% Range 0.1μΩ to 1.2GΩ Handler RS-232 InterfaceIntroduction： ■ The instrument is the first precision DC resistance tester for testing ultra-low or low parallel resistance in China. It is a miniature benchtop instrument controlled by a high-performance ARM microprocessor. The instrument has 0.02% accuracy and 0.1μΩ resolution, and 0.1μΩ~1.2GΩ measurement range. The instrument has a built-in temperature compensation interface to compensate for errors caused by temperature. ■ The instrument has a built-in 14-step comparator output with 10 passing steps, and all comparator results can be output through the Handler interface. ■ The instrument is equipped with RS-232 interface as standard and uses SCPI (Standard Command for Programmable Instrument) and Modbus protocol (Modbus has become a national standard GB/T19582-2008) for automatic sorting systems to complete fully automated in-line testing. It communicates with computers, PLCs or WINCE devices for efficient remote control and data acquisition.Features:■ Temperature compensation function. ■ High current test function (open circuit voltage <20mV). ■ Compatible with SCPI command set. ■ Superior repeated measurement accuracy. ■ Keypad lock function. ■ Data hold function. ■ Comparator function and data output function.
