DY4100 0-2000 Ohm Earth Resistance Tester Durable Ground Resistance Tester Digital Earth Tester

DY4100 0-2000 Ohm Earth Resistance Tester Durable Ground Resistance Tester Digital Earth Tester

Description:
DY4100 Digital Ground Resistance Tester can test earth resistance of various earth systems including power systems, electric equipment, lightning conductors as well as resistance value of low resistance conductor and AC voltage test.

This one has more complete functions, higher accuracy, more convenient and reliable for operation and more suitable for outdoor use with dust and wet proof structure.

Features:
- Measuring range of earth resistance: 0-2000Ω. 0/20/200/2000 ohm ±(2%+3) with 0.01 ohm
- Measuring range of earth voltage: 0-30V (3%+5)
- LED green light indicates normal operating mode
- 31/2 digit LCD display for more direct and convenient reading
- Low Battery Warning: on LCD indicates deficiency of 12V battery. LED red lighting off indicates deficiency of 1.5V battery
- Fast Response: measure earth resistance, about 5 seconds. Measure earth voltage, about 2 seconds
