Kyoritsu KEW 4202 EARTH CLAMP TESTER
Brand :
Kyoritsu
Categories :
Earth Tester
Various useful functions are available on Android devices using Bluetooth communication
• Real time measurements can be transferred, shown and saved on Android device (up to 100 measurements)• Saved 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 than the preset value
Earth /Ground resistance and Leakage current measurement functions
• The earth resistance from 0.05 to 1500 Ω can be measured without the auxiliary earth spikes in multi-earthing systems
• True RMS leakage or phase current readings from 0.1mA to 30.0A provides vital additional information in earthing networks
• Filter function offers increased immunity to electrical noise and a Noise mark appears in excessively high noisy environments
