EARTH CLAMP TESTER
MODEL 4200
• 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
Note:
A single earthing can not be measured. (Only for Multiple Earthing System)
