TESTER earth resistance (Kyoritsu K4105A)

Form

Digital earth resistance tester designed for earth resistance and earth voltage measurements on electrical installations, distribution systems and grounding electrodes.

  • material: insulated ABS housing with dust and drip resistant construction rated IP54

  • minimum quality requirements: suitable for field use, supports both precise 3-wire method and simplified 2-wire method, automatic monitoring of auxiliary spike resistance

  • standards: IEC 61010-1 CAT III 300 V, IEC 61557-1 and -5, IEC 60529 IP54

  • electrical characteristics:

    • earth resistance ranges: 20 Ω, 200 Ω, 2000 Ω

    • earth voltage range: 0–200 V AC

    • measurement method: constant current inverter around 820 Hz

    • accuracy: ±(2% + 1.0 Ω) on 20 Ω range, ±(2% + 3 dgt) on 200 Ω and 2000 Ω ranges, ±(1% + 4 dgt) on earth voltage

    • overload protection: 280 V AC/DC for resistance ranges and 300 V AC/DC for earth voltage

    • insulation resistance: ≥ 5 MΩ at 500 V between circuit and housing

    • withstand voltage: 3700 V AC for 1 minute between circuit and housing

  • power supply: 6 × AA batteries

  • dimensions: 105 × 158 × 70 mm

  • weight: approx. 540–550 g

Includes:

  • 1 × test lead set

  • 2 × auxiliary earth spikes

  • 1 × simplified measurement probe

  • 1 × carrying case

  • 1 × strap belt

  • 1 × instruction manual

  • 1 × certificate of conformity

  • 6 × AA batteries

Per piece.

Fit

  • installation method: uses the 3-wire fall-of-potential method with two auxiliary spikes, or the simplified 2-wire method when spike placement is not possible

  • electrical compatibility: suitable for verifying earth resistance and earth voltage without tripping RCDs

  • environmental compatibility: operating 0–40 °C ≤ 85% RH, storage −20 to 60 °C ≤ 75% RH, IP54 protection for outdoor field testing

  • connection compatibility: works with supplied test leads, auxiliary spikes and simplified probe

Function

  • measure earth resistance using 3-wire fall-of-potential method or simplified 2-wire method

  • measure earth voltage up to 200 V AC

  • automatic auxiliary spike resistance warning when resistance exceeds allowable value

  • supports precise testing with long leads and simplified testing with compact probe

  • built-in safety protection including overload resistance and wiring error indication

  • LCD display ensures clear readings during field measurement
