MODEL 4200

  • The earth resistance from 0.05 to 1500Ω can be measured without the auxiliary earth spikes. (The Multiple Earthing System.)
  • True RMS
  • Accurate true RMS readings of AC current including distorted waveform from 1mA to 30.0A
  • Noise Check Function
  • A function to detect current, which effects on an earth resistance measurement and display “NOISE” mark on the LCD.
  • Memory function
  • Save and display up to 100 measurement data.
  • Data hold function / Buzzer function / Back light function
  • Compliant with Safety Standards of IEC 61010-1 : CAT IV 300V Pollution degree2 Note:
  • A single earthing can not be measured. (Only for Multiple Earthing System)
