EARTH CLAMP TESTER KEW 4202 Easy earth/ground resistance measurement just clamp-on earth conductor Wireless communication with Android application Android device is not provided with instrument. Remote monitor E-mail function GPS data collection Note : A single earthing can not be measured. (only for Multiple Earthing systems.) Earth /Ground resistance and Leakage current measurement functions Various useful functions are available on Android devices using Bluetooth communication earth resistance from 0.05 to 1200 Ω can be measured without the auxiliary earth spikes in multi-earthing systems RMS leakage or phase current readings from 0.1mA to 30.0A provides vital additional information in earthing networks function offers increased immunity to electrical noise and a Noise mark appears in excessively high noisy environments time measurements can be transferred, shown and saved on Android device (up to 100 measurements) data includes measurement, GPS location and date & time Easy to check on map “When” and “Where” the measurement was made ● Comparator function on Android device informs when the measured value is lower/higher tha

Why earth measurements can be found by only clamping it? Measuring ranges Earth resistance Auto range These earth resistances, R1, R2,… Rn can be considered that they are connected in parallel. And They can be regarded as a combined resistance Rs. The Rs can be regarded small enough against Rx since a combined resistance consists of several resistances. Following is an equivalent circuit diagram of this circuit. Over-range indication Operating indication AC current （50Hz/60Hz） Auto range Rx, is defined as earth resistance under test, and R1, R2…Rn are defined as earth resistance of other...
