Product description
DY4100 ground resistance tester digital meter meter lightning protection detection shaker Package Included: 1 x DY4100 soil resistance tester 2 x auxiliary earth bar 1 x wire test 1 x single test lead 1 x instruction manual 1 x tool bag The description: The DY4100 digital earth resistance tester is a new generation tester for electricians developed by DUOYI in recent years. The circuit, structure and technique of the traditional earth resistance tester have been improved and the new design is both aesthetic and practical. It has more complete functions, higher precision, more practical and reliable for operation and more suitable for outdoor use with a dust and moisture proof structure. It can test the ground resistance of various ground systems, including power systems, electrical equipment, lightning conductors as well as the resistance value of the low resistance conductor and the AC voltage test. Earth resistance measurements from 0.01Ω to 2000Ω with a resolution of 0.01Ω. Data hold, low battery warning Complete with test leads, auxiliary earth bars, (without battery) Specification: Mode: DY4100 Resolution: 0.01 Ω Data retention: yes LED operation indicator: yes Function symbol display: yes Battery Warning: yes Earth voltage: 0-30V ± (3% + 5) Earth resistance: 0/20/200/2000 Ω ± (2% + 3) Voltage range: can support 300V AC (1 minute) Resistance range: can support 200V AC (10 seconds) Grounding resistance test requirements: a. AC working mass, the earthing resistance must not exceed 4Ω. b. safe grounding, the grounding resistance must not be greater than 4 Ω. vs. the earthing resistance of the lightning protective earth must not exceed 100 Ω. re. For joint earthing of shielded systems, the earthing resistance must not exceed 10 Ω. e. Grounding operating in direct current, the grounding resistance must be determined according to the specific requirements of the computer system. Ground tension measurement: Please turn the dial switch on the grounding voltage file "EV" and connect the test line according to the grounding test table. The earth voltage will be automatically displayed. Please make sure that the earth voltage is ≤10V. If the local voltage is> 10V. the measurement value of the earthing resistance may cause an error. At this point, the electrical equipment concerned can be switched off to reduce the grounding voltage before measurement. Earth resistance measurement: Precise measurement (with the test leads fitted) to drill the grounding pins P and C to the ground depth. 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 into the moist soil. If the ground of the grounding nail is dry, it is necessary to add water or stone or sand to wet and test)
