Double Clamp Multi-function Grounding Resistance Tester Model- Km 4237ER
KM 4237ER Double clamp multi-function grounding resistance tester is also called double clamp grounding resistance tester, The advanced grounding resistance tester integrates a variety of measurement methods. In addition to the traditional function of ancillary grounding resistance, it also has the unique function of measuring without auxiliary ground. It uses a large LCD gray screen backlight display and microprocessor technology, through the microprocessor-controlled 2-wire, 3-wire, 4-wire, selection method, double clamp method to test ground resistance. Large diameter current clamp design, using double jaw measurement technology, without the need to hit the auxiliary ground, without the need to isolate the grounding body and equipment to achieve on-line measurement.
