How to measure the current limiting resistor of electrostatic ring?
The grounding resistance tester model is ZC29B. There are three lines: 20 meters of ground pile and 40 meter stake respectively
In addition, there is a kind of clamp type meter like grounding resistance tester, will be measured a forceps, data is displayed, but very expensive, to tens of thousands of yuan a
Measurement of grounding resistance can not use a multimeter, because the meter does not have the accuracy of this requirement, grounding resistance instrument at least 0.01 euro readings,
