■ Main features
▲ The instrument adopts two power supply modes: ①AC100-240V power supply; (2) The instrument is powered by lithium battery inside, which solves the problem that no power supply can't be tested on site;
▲ The instrument has automatic test function (blind test), without selecting the current gear;
▲ The test process is controlled by the host, automatically complete self-calibration, steady flow judgment, data processing, resistance display;
▲ With perfect back potential protection function;
▲ With charging and power display functions, using large capacity lithium battery (12.6V/6000mA), to meet the needs of field testing;
▲ The longitudinal test of dc resistance of on-load voltage regulator transformer can be completed by a power supply;
▲ Instrument and test line packaging integration, easy to operate, fast measurement speed, stable measurement data;
▲ High precision, anti-interference, shockproof, easy to carry and other features;
▲ 5.0-inch 65K color LCD screen, intelligent touch, Windows menu operation tips;
▲ Built-in large capacity non-volatile memory, can store 500 groups of measurement data;
▲ Built-in high-precision real-time clock function: date and time calibration;
▲ With U disk storage function;
▲ With timing shutdown function.
