Product Details

Kyoritsu KEW Earth Tester 4106

Kyoritsu KEW 4106 is a 2/ 3/ 4-wire digital earth resistance/earth resistivity tester, equipped with a microcomputer, for measuring earth resistances and calculating earth resistivities. It has an output voltage of 10 Vrms or lower. This makes it an instrument of choice for measuring earth resistances on installations ranging from in-house wiring systems and electrical appliances to power distribution lines. Sub-results that can be shown on the display include resistance of the auxiliary earth spikes, frequency of test current, voltage and frequency of interference (noise) and residual resistance Rk.

Features and Benefits

High test current up to 80 mA yielding resolution of 0.001 Ω on 2 Ω range
Advanced filtering method based on FFT (Fast Fourier Transform) technology reduces noise interference for obtaining stable measurements
Test current frequency bands 94/ 105/ 111/ 128 Hz selectable manually or automatically
In Automatic mode, KEW 4106 will select the most suitable frequency
Measures series interference voltage / frequency
Rk function for cancelling residual resistance on the test leads
Auxiliary Earth Resistance Measurement function
Warning for excessive noise and high auxiliary earth spikes resistance
Memory function, for up to 800 measured results (for recall to display)
Communication interface (USB adapter & software) supplied, for transferring saved data to PC
Dot-matrix 192 x 64 monochrome LCD
Backlight, to view test results in dimly-lit situations
Auto-power-off function (after 5 minutes without key operation)
Battery Check function
Dimensions 167 x 185 x 89 mm
Robust design with IP54 protection
Weight 900 g approximately (including batteries)
