Product Description
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)

Grounding resistance test requirement:
a. For AC working ground, the grounding resistance should not exceed 4Ω.
b. Safety grounding, the grounding resistance should not be greater than 4Ω.
C. The grounding resistance of flashing protection grounding should not exceed 100Ω.
d. For the joint grounding of the shielding system, the grounding resistance should not be greater 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 ground voltage "EV" file, and connect the test wire according to the ground voltage test chart.
The ground voltage will be displayed automatically. Please make sure that the ground voltage is less than or equal to 10V. If the local voltage is> 10V, the ground resistance measurement value may cause an error. At this time, you can turn off the power supply of related electrical equipment and reduce the ground voltage before measurement.
Ground resistance measurement:
Accurate measurement (using the equipped test lead) to pierce the P and C grounding needles to the ground depth.
They are arranged in a line with the grounding equipment and are separated from each other by 5 to 10 meters.
(Note: Make sure to insert the grounding pin into the damp soil. If the soil of the grounding pin is dry, you must add water or stones or sand to be wetted and test)
