DY4100 Digital Megohmmeter Megger Meter Insulation Earth Ground Resistance 0-2000 Ohm Voltage Tester
Description:
The digital ground resistance tester DY4100 is a new generation tester developed by DUOYI for electrical practice in recent years.
The circuit, structure and technology of the traditional grounding resistance tester have been improved, and the new design is both beautiful and practical.
The machine has more complete functions, higher precision, more convenient operation, more reliable, and is more suitable for outdoor use with dust-proof and moisture-proof structure.
It can test the grounding resistance of various grounding systems, including power systems, electrical equipment, flashing rod and low-resistance conductor resistance and AC voltage tests.
The ground resistance measurement range is 0.01Ω to 2000Ω, and the resolution is 0.01Ω.
Data retention, low battery warning.
Equipped with test wire, auxiliary ground rod (not including battery).

Grounding resistance test requirements:
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)

Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-3cm measuring deviation due to manual measurement.
