Product Introduction

ETCR3650 Grounding Down Lead Conduction Tester is suitable for measuring the on-resistance value between the grounding down lead of power equipment and the grounding down lead(or adjacent equipment). It can effectively detect the increase in resistance caused by various reasons in the lead resistance between electrical equipment and the grounding grid, in order to avoid equipment grounding operation. The power industry standard DL/T475-2017 "Guidelines for the Measurement of Characteristic Parameters of Grounding Devices" stipulates that special instruments should be used for measurement of electrical conductivity, with a resolution of 1mΩ and an accuracy of not less than 1.0.
ETCR3650 Grounding Down Lead Conduction Tester is specially used for the electrical integrity test of grounding devices, and its technical indicators meet or exceed the requirements of relevant standards. The instrument consists of host, test line, etc. The instrument adopt with microprocessor technology and precision four-wire method for measuring, which is accurate and reliable. The instrument has two power supply modes: AC220V and large-capacity lithium battery, and two measurement modes: automatic measurement and manual measurement. The instrument adopt with 5 inch true-color high-definition touch screen with backlight adjustment function, which is clear visibility in strong light. The instrument shell adopt with waterproof protective box, which is anti-collision, anti-fall, waterproof, strong, safe and durable. The instrument with a built-in printer, Bluetooth communication and USB interface.
The instrument is simple and convenient to operate, high accuracy, fast-speed in testing, good retestability, and intuitive readings. It is an ideal special instrument that meet the requirements of the regulation, which greatly facilitate the development of test project and improve work efficiency.
1.The instrument has two power supply modes: AC220V and large-capacity lithium battery, meet the requirement of user for various occasions.
2.Two measurement modes: automatic measurement: Automatically select testing current based on load and manual measurement: 4 gears for testing current.
3.Test current gear: AUTO, 10A, 5A, 1A, 100mA
4.Max. output voltage 24V, max. test current 10A, fast-speed test.
5.Adopt with 5 inch true-color touch screen, dual use: touch screen/button for measuring operation.
6.Built-in printer, can print the test result on site.
7.With Bluetooth communication, can perform testing operation or view test result on your phone after installing App.
8.Alarm function, setting resistance alarm threshold.
9.USB communication interface.
10.Equipped with discharge function, automatically discharge after testing, with clear discharge indication to avoid misoperation.
