| Earth Resistance Tester DER 2571 B |
|
|
 |
This Digital tester measures Earth Resistance, Resistively & Voltage. |
|
Capability of preventing disturbance from earth voltage, promise normal test without
open the circuit |
|
If auxiliary earth resistance of potential terminal Rp 50k and of current terminal Rc 2k,
it has no influence on measuring |
|
If earth return circuit is opened, OPEN CIRCUIT is given on LCD |
|
Range up to 2000. |
