The product description

Product name: programmed ground resistance tester product model: lk-7350

■ LK series grounding resistance tester is used to measure the grounding resistance inside the electrical equipment, which reflects the resistance between the exposed conductive parts of the electrical equipment and the general grounding terminal of the electrical equipment. In order to eliminate the impact of contact resistance on the test, the ground resistance tester adopts the four-terminal measurement method, that is, the exposed conductive part of the measured electrical appliance and the total ground terminal with the current, and then measure the voltage at both ends, to calculate the resistance value

Detailed introduction:

The performance characteristics of(LK7305)
■ constant current linear amplification output

■ front panel software correction, high accuracy

■ optional with RS232, standard with PLC interface

■ keyboard lock function

*7305 can be connected with 7110/7122 to form a two-in-one voltage grounding and three-in-one voltage insulation grounding tester, which is convenient and flexible.
