 DC Resistance Tester Quick Description: 
 ETZZ-3A DC Resistance Speed ??Tester (Micro Europe dollars) to replace the current single, high-precision double bridge replacement. Is a measure of power transformers and large motors and other inductive load switch resistance and low contact resistance, the interface resistance of the weld wire and cable, or the ideal instrument, the measurement speed of a hundred times faster than the bridge. Apparatus built in rechargeable battery pack (12V), AC, DC, to facilitate on-site and field testing. 

 DC Resistance Tester feature quickly: 
 (1) test speed: This instrument uses high-power integrated circuits, constant current output 3A current can quickly reach a stable value of the measurement, thereby greatly reducing the measurement time than single, double bridge hundreds of times faster measurement of rapidity. 
 (2) AC and DC: The instrument built-in rechargeable bottles of environmentally friendly maintenance-free, AC-DC dual-use, especially suitable for outdoor use without AC 220V power supply situation. Is a similar product (referring to 3A current source directly below the resistance meter) upgrading the ideal choice. 
 (3) functional tests: In addition to showing the time of the instrument to measure resistance, but also can display the test current, test time, ambient temperature. Sound and light alarm, automatic discharge elimination alone. 
 (4) high degree of intelligence: The application of SCM control equipment, the use of dual-programmable comparison, data analysis, and anti-arcing circuit. Large blue LCD display, menu operation, man-machine dialogue, the reading operation is extremely convenient, quick. 
 (5) Import nice chassis: the adoption of international standards for the equipment ABS plastic instrument case (or advanced aluminum box), compact and user-friendly panel layout, innovative and reasonable, the volume small size, light weight, easy to carry.
