E-Clip 1 / E-Clip 2 2. Current Clamps Description of current clamps The E-Clip 1and E-Clip 2 are 1000/1 ratio current clamps for measuring alternating currents in the range from 1 mA to 1000 A (depending on the type). They can be connected to any power analyzer, energy analyzer, harmonics analyzer, multimeter, earth resistance meters, electrical installation testers and other measuring instruments with compatible voltage or current inputs.
E-Clip 1 / E-Clip 2 Current Clamps 3.2. Cleaning Use a soft cloth moistened with soapy water or alcohol to clean non-metallic surface of the current clamps and leave them to dry totally before using it. Notes! • Do not use liquids based on petrol or hydrocarbons! • Do not spill cleaning liquid over the current clamps! To clean jaw cut surfaces use slightly oiled soft cloth. 3.3.
E-Clip 1 / E-Clip 2 Current Clamps Clamp current transformer must always have a low impedance load on its secondary side. This loading is realized with an A-meter (for current sensors with current output). Current clamp with voltage output already contains the load resistor and its output voltage is proportional to measured current. The N1:N2 ratio (primary to secondary winding turns ratio) defines the step-down current ratio and sensitivity of current clamps.
