PRODUCT ADVANTAGES

Earth resistance measurement

Accurate measurement (with the equipped test leads) to puncture the P and C grounding pins to the depth of the ground. They are arranged in a straight line with the grounding equipment and are spaced 5 to 10 meters apart. (Note: Make sure the grounding pins are inserted in the wet soil. If the soil of the grounding nail is dry, it is neceary to add water or stone or the sand to be wet and test)

Grounding resistance test requirements:

a. AC working ground, the grounding resistance should not exceed 4Ω,

b, safe working ground, the grounding resistance should not be greater than 4Ω,

c. DC working grounding, grounding resistance should be determined according to the specific requirements of the computer system;

d, the grounding resistance of the lightning protection ground should not exceed 100Ω;

e. For jointed grounding of shielded syst, the grounding resistance should not be greater than 10 Ω.

Ground voltage measurement

Please turn the dial switch to the grounding voltage "EV" file and connect the test line according to the grounding voltage test chart. The ground voltage will be automatically displayed. Please make sure that the ground voltage is ≤10V. If the local voltage is >10V, the grounding resistance measurement value may cause an error. At this point, the relevant electrical equipment can be powered off to reduce the ground voltage before measuring.
