NR2100 Ground Resistance Tester
The grounding resistance of electrical equipment is an important part to ensure personal safety and the normal operation of electrical equipment. In recent years, equipment accidents caused by grounding problems of electrical test equipment have occurred from time to time, and attention should be paid. The device can measure the grounding resistance value, the ground voltage value and the soil resistivity of various grounding devices, and it is one of the most commonly used test equipment for power systems.
◆ Large-character LCD digital display, easy to read;
◆ The auxiliary grounding resistance is less than 10KΩ, which has no influence on the test;
◆ Battery powered, undervoltage indication.
◆ Measuring range and constant current value (effective value)
Voltage: AC 0-20V
Resistance: 0-2(10mA) 2-20(10mA) 20-200(1mA)
◆ Measurement accuracy
0-0.2Ω ≤3%±1d
0.2-200Ω ≤1.5%±1d
1-20V ≤3%±1d
