Grounding Tester Kyoritsu 4106

Grounding Tester Kyoritsu 4106
Features:
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.
