Kyoritsu 4202 Earth Clamp Grounding Tester with Bluetooth

Various useful functions are available on Android devices using Bluetooth communication

The earth resistance from 0.05 to 1500Ω 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
Memory function up to 100 data
Bluetooth communication
