Save time with this earth resistance clamp – no need to lay out auxiliary spikes

Capable of measuring earth resistance levels between a range of 0.05 and 1500Ω with high accuracy, it can also be used to gain a reading of AC current levels. The KYORITSU 4200 includes large jaws which are designed for clamping directly onto a targeted testing application.

KEY BENEFITS

  • Save time with this earth resistance clamp – no need to lay out auxilary earth spikes
  • For measuring earth spikes in systems with multiple earthing points

    You can use the KYORITSU 4200 Digital TRMS Earth Resistance Clamp to carry out earth resistance testing procedures without the need to use auxiliary earth spikes.

    It is capable of measuring earth resistance levels between a range of 0.05 and 1200Ω with high accuracy, it can also be used to gain a reading of AC current levels. The KYORITSU 4200  includes large jaws which are designed for clamping directly onto a targeted testing application.

    Calibration of the Kyoritsu 4200 can be checked before taking measurements by using the supplied Test Fixture/Resistor.

    With built in noise checking, the KYORITSU 4200 Digital TRMS Earth Resistance Clamp is able to filter out noise problems and maintain accurate results. These results are also able to be stored directly on the tester (it features memory for 100 readings) and other additional features unique to this earth resistance clamp meter include a buzzer function, data hold and a backlit screen.

    KYORITSU 4200 Digital TRMS Earth Resistance Clamp Features:

    • 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
