Overview

The K4118 instrument is microprocessor-controlled and includes useful features such as mains voltage measurements, neon indication of current wiring status and a lock down test button for hands-free operation.

An added feature is a 200 ohm earth electrode resistance test range to check that the earth electrodes comply with the IEC wiring regulations. The Major Tech K4118 Digital Earth Loop Impedance Testers is the most technologically advanced series of such instruments available and are designed to comply with IEC 61557-1 regulations.

This instrument offers convenient and accurate measurements of Earth Loop Impedance at the origin (Ze) and at various points throughout the electrical installation (Zs).

The K4118 offers three pre-selectable Loop Impedance ranges and three pre-selectable Prospective Short Circuit (PSC) ranges.

When the external earth probe is utilised, it is possible to measure the phase to Earth Loop Impedance of exposed metalwork, such as light fittings, trunking and where applicable conduit.
