DC resistance tester
기능적 특성
● Large output current, 넓은 측정 범위, 작은 크기, 가벼운 무게, 간단한 조작;
● Fast test speed, 높은 측정 정확도, good retest, 강력한 간섭 방지 능력;
● With perfect protection circuit and discharge alarm function, 오작동을 줄이다, strong reliability;
● High-speed microcontroller is used to automatically complete steady current judgment, data acquisition and resistance display;
● Wide temperature 110*60 large screen Chinese LCD display, outdoor bright light display content is still clearly visible;
● Built-in large capacity non-volatile memory, 저장할 수 있다 500 groups of measurement data, with printing function or USB output function (only two options);
● Built-in high-precision real-time clock function: date and time calibration;
● The instrument uses two power supply modes: mains AC220V power supply and built-in battery power supply, using Japan Panasonic 16Ah large capacity battery, intermittent test up to 8 시간, do not shut down continuous full current test up to 2.5 시간, to solve the problem of no power and can not be tested on site;
● The test process is controlled by microcomputer, which automatically completes self-calibration, steady current judgment, data processing and resistance display;
● With perfect anti-potential protection function;
● Automatic switch between AC and DC power supply, with charging indicator function, overcharge protection;
● Longitudinal test of DC resistance of on-load regulator transformer can be completed with one power supply;
● Suitable for the rapid measurement of DC resistance of transformers with voltage levels of 110kV and below.
