The Kyoritsu 4105A is designed in such a way that the influence of the earth voltage and earth resistance of the auxiliary spikes are neglected under the earth resistance test. A low measuring current of 2mA allows earth resistance tests to be performed without tripping earth leakage current breakers. The 4105A also has the ability to measure earth voltage, up to 200V AC.
Small and lightweight, the Kyoritsu 4105A is both dust and drip proof, conforming to the IP54 standard. The instrument is also schok resistant and designed to meet IEC 61010-1 safety standard. The Kyoritsu 4105A is supplied with earth resistance test leads, measurement probe, auxiliary spike kit, batteries, a shoulder strap and a carry case.
Measures earth resistance up to 2000Ω.
2mA measuring current (prevents tripping of earth leakage current breakers).
Accurate testing with minimal interference from earth voltage and spike earth resistance
