Detail New Earth Resistance & Resistivity Tester 4106 KYORITSU

New Earth Resistance & Resistivity Tester 4106

" High test current up to 80mA yielding resolution of 0.001© on 2© 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.

" Large Graphic Display with backlight for readings in poorly illuminated areas.
" Up to 800 measurement results can be saved in the memory and recalled on the display.
" The stored results can be transferred to a PC using the " KEW Report" software and a USB adaptor ( Model 8212-USB) which are included.
" Robust design with IP54 protection.
