Description

DC resistance tester

Caractéristiques fonctionnelles
● Large output current, wide measuring range, petite taille, poids léger, opération simple;
● Fast test speed, haute précision de mesure, good retest, forte capacité anti-interférence;
● With perfect protection circuit and discharge alarm function, reduce misoperation, 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, peut stocker 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 heures, do not shut down continuous full current test up to 2.5 heures, 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.
