Computer conductor resistance tester

Performance Characteristics of Product ◆Executive standard: GB/T4074.5-2008/IEC60851-4; Inspection standard: JB/T4279.2-2008 ◆Used to measure conductor with nominal diameter ≥0.010～9.000mm or various round or flat copper and aluminum wires and other metal wires with DC current resistance of 1μΩ～3MΩ; ◆Combination of intelligent DC conductor resistance measuring meter and DC resistance test fixture with sample straightening function; ◆Both potential fixture and current fixture are made of copper; ◆The application of microcomputer control allows for full-automatic completion of test; ◆Select tap position automatically according to the resistance value of sample, and after clamping samples, current temperature resistance value would be displayed; ◆Temperature sensor would automatically sense the temperature; after inputting material number, diameter or cross section area of sample to be tested, the instrument will automatically work out the resistance value (R20 resistance value), real-time resistivity and R20 resistivity at 20℃; ◆According to the market need, setting for six different materials is available, it is allowed to input at will the temperature coefficient not specified in the standard; ◆Chinese LCD will intuitively display various parameters and measurement results; ◆The application of software facilitates instrument’s on-line operation and control as well as data analysis and comparison; ◆All test data can be automatically transmitted to upper computer, and be saved and analyzed by DMS-15 quality inspection data management system for enameled winding wire.
