What's the difference between a ground resistance tester and a shake meter?
The utility model realizes the on-line measurement without the need to hit the auxiliary earth pole without isolating the grounding body from the equipment. The machine has intelligent measurement function, can store and browse the measurement results, and show the use of Chinese characters.
The grounding resistance of the grounding test device of GY-318 double jaw grounding resistance tester is applicable to all kinds of equipment and building the. The soil resistivity under various conditions can also be measured. In addition to the traditional function of measuring the grounding resistance of the earth electrode, the instrument has the unique function of non auxiliary pole measurement, and has changed the traditional measuring principle and means of the test grounding resistance.
The auxiliary ground resistance affects the amount of change, and when the auxiliary ground resistance changes from 500 to the specified value below, the amount of change allowed shall not exceed the specified value in the table
