■ main features of handheld DC resistance tester

▲ the instrument adopts two power supply modes: ① AC100-240V power supply; ② The instrument is powered by lithium battery, which solves the problem that it cannot be tested on site due to no power supply;

▲ the instrument has automatic test function (blind test), without selecting current gear;

▲ the test process is controlled by the host, which automatically completes self calibration, steady current judgment, data processing and resistance value display;

▲ it has perfect back EMF protection function;

▲ it has the functions of charging and power display, and adopts high-capacity lithium battery (12.6V / 6000ma) to meet the needs of field test;

▲ the longitudinal test of DC resistance of on load voltage regulating transformer can be completed at one time;

▲ the instrument is integrated with the test line, with simple operation, fast measurement speed and stable measurement data;

▲ high precision, anti-interference, shockproof and easy to carry;

▲ 5.0 inch 65K color LCD screen, intelligent touch, windows menu operation prompt;

▲ built in large capacity nonvolatile memory, which can store 500 groups of measurement data;

▲ built in high-precision real-time clock function: date and time calibration can be carried out;

▲ with USB flash disk storage function;

▲ it has the function of timed shutdown.
