Current clamp adapters Earth clamps Article number: ERTa7 626 000 309 Article number: Miniclamp 626 000 637 Earth clamps (utility-city measurements) It is very important to determine the quality of each separate earth electrode, when more than one earth system is parallel connected. In general it is difficult to release the mechanical connection of these electrodes because of rusty parts like screws, bolts etc. That is why the ERT-S and the Eurotest instruments are equipped with the UTILITY mode. This function offers the possibility to use a current clamp for measurements of such earth electrodes without disconnected those. The ERTa7 has a range up to 1000A and the miniclamp up to 200A ERTa7 Specifications Miniclamp Specifications ERTa7 Ratio Max. jaw opening Dimensions Weight Miniclamp Ratio Max. jaw opening Dimensions Weight Output signal Frequency Output 1000A:1A 52 mm. 10 x 215 x 40 mm. ± 610 mm. 200A:200mA 15 x 17 mm 90 x 40 x 23 mm. ± 115 gram 1A at nominal input current 40 – 5000 Hz 1,5 meter cable with 4 mm. plugs 76 www.nieaf-smitt.nl
