ETCR Series Clamp-on Earthing Resistance Tester

1. Product Introduction

ETCR Series Clamp-on Earthing Resistance Tester is widely used to measure ground resistance and loop resistance in electric power telecommunications meteorology oil construction and industrial electrical equipment. When measuring the circuit grounding system without disconnecting ground deflectors without auxiliary electrode it’s safe and fast. It can measure the ground fault which difficult to be measured by traditional methods because the ETCR Series Clamp-on Earthing Resistance Tester can measures the ground resistance and ground lead resistance.

2. Characteristics and functions:

● After boot can immediately enter into the test

● Using the most advanced processing algorithms and digital integration technology

● Light weight and smart is portable

● New design 6 keys in the plant straight performance.

● Add the sound and light alarm function: “Beep--Beep--Beep--”.

● Add the jamming signal recognition function “Beep--Beep--Beep--”.

● The measure range extend to 0.01Ω-1200Ω.

● Can store 99 group data less power dissipation maximum boot the working current is less than 50mA.
