Ground Resistance Tester manufacturers / High Ground Resistance Tester Ground Resistance Tester manufacturers - the TK2571 high ground resistance tester measure the grounding resistance of various devices for electric power, telecommunications, railway, petroleum, chemical, communications, mining and other sectors as well as measurement low resistance conductor resistance, the table can also measure soil resistivity and ground voltage. 【Details】 the TK2571 high ground resistance tester brief introduction to performance characteristics of the instrument compared with the traditional hand-ground resistance meter has the following characteristics: a, the application of a DC / AC conversion technology, set of three-terminal button, four-terminal-button measurement as a whole, the use of power can post, DC. b, phase-locked loop synchronization tracking detector, and switched-capacitor filters, anti-interference ability. c abandon the traditional manual Dynamo, do not need a human to do work. d, do not need to manually adjust the balance, at a glance panel touch membrane key operation, LCD digital display makes the measurement is very convenient and rapidly, eliminating the the pointer instrument's visual error. e, allowing the auxiliary grounding resistance, better ensure the accuracy, high resolution. f, in addition to ground resistance testing, can test the low resistance value, the soil resistivity and AC voltage to ground. Use the TK2571 high ground resistance tester ground resistance tester manufacturers - I. Introduction 1, use this table apply to electric power, telecommunications, railway, petroleum, chemical, communications, mining and other sectors measuring the ground resistance of various devices and measurement of low resistance conductor resistance, the table can also measure soil resistivity and ground voltage. , The Working Principle on the grounds inside the DC / AC converter DC into AC low frequency constant current circuit after the auxiliary earth electrode C and the measured object E, the measured object generates an alternating voltage drop, the auxiliary grounding The pole P into the AC amplifier into the header been tested. With the override switch can be obtained three different limit the amount of: 0 to 2Ω, 20Ω, 200Ω. 3, the performance characteristics of the instrument compared with the traditional hand-ground resistance meter, has the following characteristics: application of a DC / AC conversion technology, set the button of the three-terminal measurement of the four-terminal button, the use of power can post, DC dual-use. b, phase-locked loop synchronization tracking detector, and switched-capacitor filters, anti-interference ability. c abandon the traditional manual Dynamo, do not need a human to do work. d, do not need to manually adjust the balance, at a glance panel touch membrane key operation, LCD digital display makes the measurement is very convenient and rapidly, eliminating the the pointer instrument's visual error. e, allowing the auxiliary grounding resistance, better ensure the accuracy, high resolution. f, in addition to ground resistance testing, can test the low resistance value, the soil resistivity and AC voltage to ground.
