Product Detail:
Application:
It can be used for measuring earth resistance and earth voltage of various earth installations as well as the resistance value of low resistance conductors
Features:
* Capability of preventing disturbance from earth voltage, promise normal test without open the circuit.
* If auxiliary earth resistance of potential terminal Rp=50kΩ and of current terminal Rc=2kΩ, there is no influence on measuring .
* If earth return circuit is opened, the "Test" indication light turns from red to yellow.
