Earth Testers
Earth Resistance & Resistivity Tester High test current up to 80mA yielding resolution of 0.001Ω on 2Ω range. • Advanced Filtering method (based on FFT Fast Fourier Transform) reduces noise interference for obtaining stable measurements. • Automatic and Manual selection of the Test Current Frequency in four bands (94/105/111/128Hz). In Automatic mode, KEW 4106 will select the most suitable Frequency. • Several sub-results can be shown on the display: Resistance of the Auxiliary Earth Spikes, Frequency of Test Current, Voltage and Frequency of Interference (noise), Residual Resistance Rk, etc. • Warning for excessive noise and high Auxiliary Earth Spikes resistance.

KEW 4300 is simplified earth resistance tester (based on 2-pole method) that can be used for various distribution lines and electrical appliances and it also can measure AC/DC voltage. (As for AC Voltages, true rms values can be obtained.) • 200/2000Ω (2 ranges): auto-ranging. • Warning buzzer triggered at 100Ω or less. • LED lights up when a large earth voltage is detected. • Live circuit warning when 30V or higher voltage is detected. (KEW 4300 detects voltage even when measuring resistances.) • LED light for illuminating measurement points.(It turns on/off automatically in relation to the ambient brightness.) • Small test current (max 2mA) not triggering RCD.
