Product Description Ohm Meter Loop Resistance Tester Circuit Breaker Analyzer Introduction The micro-ohmmeter adopts high-frequency switching power supply technology and digital circuit technology, conforming to the latest power system standard IEC62271, and is a special instrument for measuring the loop resistance of switch control equipment. The test current of the instrument is DC 400A/200A/100A recommended by the national standard. It can measure the loop resistance at this current value and display the result digitally. The instrument has high accuracy and good stability, and can meet the requirements of on-site maintenance of high-voltage switches in most power systems and loop resistance measurement in high-voltage switch plants. Features1. Using the latest power supply technology, the tester can continuously output large current to obtain accurate measurement results.2. Even in the case of strong interference, the final test data will be stably displayed on the LCD screen.3. Long service life: All precision resistors used in the tester can reduce the influence of temperature on the measurement results.4. Small size and light weight5. All test results of the tester can be printed through the built-in micro printer of the tester, which can be uploaded to the PC computer and then converted into MS WORD documents.Index 1Measuring range0-1999.9 μΩ Resolution:0.1 μΩ 2Measuring currentDC 100A/200A for different selection 3Measuring precision0.5 %RGD+0.05%FS 4Display modeLCD 5Data storageSave no more than 100 groups of data 6Data connectionRS232 computer interface 7Rated power supplyAC220V 8Size340mm× 280mm × 210mm 9Environment temperature-10 oC~+40 oC 10Relative humidity<80% More details
