Description
M312N | METRAclip EARTH, earthing tester, Bluetooth and protocol software
The measuring clamp is "generator and measuring clamp in one device" and is used to control the resistance of any conductive system that has the properties of a loop. The following measurements are possible:
- Measurements of the earth resistance if this earth with its equipotential bonding conductor is in series with the earth loop
- Earthing measurements, for example via the earth cable that connects overhead line masts for energy transmission or for telecommunications
- Measurements on distributed earths with the same ground plane
Lieferumfang
