Introduction: DY4100 Digital Ground Resistance Tester Digital earth resistance tester DY4100 is a new generation tester for electrician practice which is developed by DUOYI in recent years. The circuit, structure and technique of traditional earth resistance tester have been improved and the new design is both fine-looking and practical. 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. It can test earth resistance of various earth systems including power systems, electric equipments, lightning conductors as well as resistance value of low resistance conductor and AC voltage test. Ground resistance measurements from 0.01Ω to 2000Ω with 0.01Ω resolution Data hold, low battery warning Complete with test leads, auxiliary earth bars, (not include battery) ![]() ![]() Specifications: MODEL:DY4100 Earth Ground Resistance:0/20/200/2000Ω ±(2%+3) Earth Voltage:0~30V ±(3%+5) Resolution:0.01Ω Data Hold:yes Working LED Indicator:yes Function Symbol Display:yes Low Battery Warning:yes General Characteristics Power:AA1.5Vx6(UM3) (not include battery) Package Included: 1. 2*auxiliary earth bar 2. testing wire red 15-meter testing wire yellow 10-meter testing wire green 5-meter testing wire 3. 1*simple testing wire red 1.6-meter testing wire green 1.6-meter testing wire) 4. 1*instruction manual 5. 1*tool bag | ![]() Features: Resolution:0.01 ohm Data Hold:yes Working LED Indicator:yes Function Symbol Display:yes 1.
