General Specifications
IEC61010-1
CAT Il600V
IEC61010-1
CAT lII300V
The K4118 and K4120 instruments are microprocessor-controlled and includes useful features such as mainsvoltage measurements, neon indication of current wiringstatus and a lock down test button for hands-free operation.An added feature is a 200 ohm earth electrode resistance testrange to check that the earth electrodes comply with the IECwiring regulations. The K4118 and K4120 Digital Earth LoopImpedance Testers are the most technologically advancedmeters of such instruments available and are designed tocomply with IEC 61557-1 regulations. These instrumentsoffer convenient and accurate measurements of Earth LoopImpedance at the origin (Ze) and at various points throughoutthe electrical installation (Zs).
