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 necessary 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 systems, 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.

Customer Reviews
Material at the top. Ultra-precise measurement check with a large brand device that costs 5 times more expensive. Top Package. Small transport bag provided. Frankly super delighted high quality material I recommend. Top customer service too. Quick and effective rest
Have you a manual in german?
works well
The product arrived 2 days late. I ordered the Russian government from a warehouse, but I assume that I flew in from the near abroad. Checked the grounding, the device shows. Also measured on the resistor 50 om showed, 49 with something. I'm still satisfied, I went over 4800 rubles. For home measurements in the private sector.
DHL shipment up to Polish 2 days. Meter well packed, soft wires and good quality plastics. The photo shows everything you need, i.e. the correctness of the measurement. I am satisfied.
