                        Description:
                         
                        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)
                         
                        Specification:
                         
                        Mode: DY4100
                        Resolution: 0.01Ω
                        Data Hold : yes
                        Working LED Indicator: yes
                        Function Symbol Display: yes
                        Tow Battery Warning: yes
                        Earth Voltage: 0-30V ±(3%+5)
                        Earth Ground Resistance: 0/20/200/2000Ω± (2%+ 3)
                        Voltage range: can withstand 300V AC (1 minute)
                        Resistance range: can withstand 200V AC (10 seconds)
                         
                        Grounding Resistance Test Requirements:
                        a. AC working ground, the grounding resistance should not exceed 4Ω.
                        b. safe working ground, the grounding resistance should not be greater than 4Ω.
                        c. the grounding resistance of the lightning protection ground should not exceed 100Ω.
                        d. For jointed grounding of shielded systems, the grounding resistance should not be reater than 10Ω.
                        e. DC working grounding, grounding resistance should be determined according to the specific requirements of the computer system.
                         
                        Ground Voltage Measurement:
                        Please turn the dial switch to the grounding voltage "EV" file and connect the test line according to the grounding voltage test chart.
                        The ground voltage will be automatically displayed. Please make sure that the ground voltage is ≤10V. If the local voltage is >10V.
                        the grounding resistance measurement value may cause an error. At this point, the relevant electrical equipment can be powered off
                        to reduce the grounding voltage before measuring.
                         
                        Earth Resistance Measurement:
                         Accurate measurement (with the equipped test leads) to puncture the P and C grounding pins to the depth of the ground.
                        They are arranged in a straight line with the grounding equipment and are spaced 5 to 10 meters apart.
                        (Note: Make sure the grounding pins are inserted in the wet soil. If the soil of the grounding nail is dry, it is necessary to add water or stone or the sand to be wet and test)
                         
                        Package Included:
