Product Detail:
Application:
It can be used for measuring earth resistance of various earth installations and the resistance of low resistance conductors,and also be used for testing earth resistivity and testing earth voltage
Features:
* 3 1/2 LCD digital display, big screen for easy reading
* Capability of preventing disturbance from earth voltage, promise normal test without open the circuit
* If auxiliary earth resistance of potential terminal Rp and of current terminal Rc are as below value:
Rp=50kΩ
Rc=1kΩ (range 0.00~19.99Ω)
Rc=10kΩ (range 20.0~199.9Ω;200~1999Ω)
There is no influence on measuring.
* If earth return circuit is opened, OPEN CIRCUIT is given on LCD
* Battery supply, low battery indication
