KYORITSU 4202 Earth Clamp Tester
Various useful functions are available on Android devices using Bluetooth communication
| Free Android software “KEW smart 4202” is available on “Google Play Store” <System requirement>
|
(*) Please search “KEW Smart” in Google Play Store. Communication charge may be incurred separately to download application.
- 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
