Product Introduction

ETCR2150 Loop Resistance Tester, also known as loop circuit Resistance Tester, which is used for measurement of loop resistance of lightning protection Device and leakage current, judging whether the connection of the lightning protection device is reliable and earth current and troubleshooting. In the loop resistance measurement, no need to disconnect the loop down lead, you can measure the loop resistance and the leakage current at the same time by using clamp meter to clamp the line. This clamp meter fully meets the scope stipulated in the National Meteorological Bureau's Order No. 38 [Lightning Protection Device Testing Qualification Management Measures], and is widely used in construction quality inspection stations, supervision companies, construction units, lightning protection companies, electric power departments, etc. The resistance, current, and test time of are displayed on the screen, and the test results are clear.Equipped with rechargeable lithium batteries, it is easy to use.Sound and light alarm function, data storage, data hold function.Clock function, display the current test time.USB interface data upload function.
