Product Description Features RK2678X earthing resistance tester is suitable for measuring the resistance value between metallic part of motors, appliances, instruments, meters, domestic apparatuses that are supplied power with power grid, and their protective earthing terminal. The tester has two scales of testing resistance value (200 mΩ or 600 mΩ). The testing time can be set between 0～99s. when the measured resistance value is larger than the preset resistance value, it has audible and visible warning function, and overcurrent (>AC30A) protection function. This tester uses the principle of divider for measurement, and fluctuation of testing current cannot affect measurement accuracy, therefore, it has the following advantages: accurate measurement, convenient operation, small volume and low requirement to power. The tester uses 3½ digital display and the reading is convenient and simple, and reliability is very high. The new optional function of broken wire warning (i.e. open circuit warning) can be very easy to know whether the tester is working in normal test status, and a user can select this function upon actual demand. Technical specifications Range of measurement 0～200mΩ±(5%+ 2 scales)　(25A) 200～600mΩ±(5%+ 2 scales)(10A) Testing time 0～99s(continually adjustable) Testing voltage ≤ AC 12V/6V（RK2678Y） Testing current AC 5～30A±5% Overcurrent warning > AC 30A Warning resistance value 0～200mΩ±( 5%+ 2 scales)(AC 25A)continually adjustable 200～600 mΩ±( 5%+ 2 scales)(AC 10A) continually adjustable Operating conditions Temperature 0～40℃ Relative humidity ≤ 80％RH Power supply AC　　220V±10％　 50Hz Overall size 315mm×250mm×165mm Weight 15kg 　 ***THIS IS A 220V MACHINE. US CUSTOMER NEEDS POWER TRANSFORMER TO USE THE MACHINE.***
