|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 or 600)...|
|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
|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..|
