The Kyoritsu 4106 Ground Resistance Tester is a reliable and high-accuracy provider that is capable of measuring earth resistances and calculating earth resistivities. The Kyoritsu 4106 has a low output voltage of approx or less than 10V RMS and, therefore, can be applied to do its stuff earth resistances in version to gift distribution lines, in-residence wiring systems, and electrical appliances.
The Kyoristu 4106 is specified to feign earth resistances from 0.001 to 200 k across six exchange ranges. The instrument can acquiesce a tall exam current, happening to 80mA, to accommodate a sound of 0.001 upon the 2 range. Advanced filtering is provided, using a Fast Fourier Transform (FFT) implementation, to shorten noise interference and get stable measurements. The measurements can be saved in the memory (going on to 800 measurements) and recalled upon the display. Saved results can additionally be transferred to a PC via the provided USB adaptor and the included reporting software.
The Kyoristu 4106 comprises three AC ranges (20mA/200mA/200A), as adeptly as both automatic and manual selection of the exam current frequency (94/105/111/128Hz). Earth resistivity can be automatically calculated after setting the set against along amid the count earth spike (Wenner method).
Featuring a large graphic display also backlight, the Kyoritsu 4106 is expected to withstand tough environments, conforming to an IP54 rating. The meter is supplied furthermore than than test leads, an adding earth spike set, a USB adaptor as soon as reporting software, batteries, and a carry warfare. Get this tester at an affordable price in Bangladesh.
Key Features:
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 Spike 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.
