TL5703 Ground Resistance Tester

■ Ground resistance tester is used to measure the grounding resistance within the electrical equipment, which reflects the (contact) resistance between each exposed conductive part of the electrical equipment and the total grounding terminal of the electrical equipment. Ground resistance tester in order to eliminate the impact of contact resistance on the test, the four-terminal measurement method, that is, in the test between the exposed conductive part of the electrical equipment and the total grounding terminal plus the current, and then measure the voltage between these two ends, calculated its resistance value.

TL5703 type grounding resistance tester is in accordance with GB ﹑ IEC ﹑ ISO ﹑ BS ﹑ UL ﹑ JIS and other international and domestic safety standards and design, grounding resistance index is a measure of the safety performance of a variety of electrical equipment, one of the important indicators. It is in the case of high current (25A or 10A) on the grounding circuit resistance measurement, but also on the grounding circuit to withstand high current indicators of the test, in order to avoid the decline in insulation performance (or damage) when the personal injury. This tester is developed and produced to meet the above requirements and provide high-performance testing instruments for production workshops and experimental departments. This instrument does not require high power supply voltage, high measurement accuracy, fast speed, easy to use, especially suitable for demanding laboratories and automatic testing line use. The disconnection alarm selection function (i.e. road alarm) can conveniently know whether the instrument is working in the normal test state, and the user can choose whether to need this function according to the actual needs. The instrument adopts three-and-a-half digits display, easy to read, with optimized design, the whole machine has high reliability and stability.

This product meets GB4706.1-2005, GB9706.1-2007 and other safety standards test, in line with the requirements of JJG984-2004 safety measurement and verification regulations.
