Kyoritsu 4106 

  • 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. 
  • Warning for excessive noise and high Auxiliary Earth Spikes resistance. 
  • Three AC current ranges 20mA/200mA/200A. 
  • Large Graphic Display with backlight for readings in poorly illuminated areas. 
  • Robust design with IP54 protection. 
  • Up to 800 measurement results can be saved in the memory and recalled on the display.
