kyoritsu kew 4202

category: earth tester

quick overview:

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
