Kyoritsu 4102A-H Earth Tester – Hard Case Model


The Kyoritsu 4102A-H tester performs three-pole earth resistance and two-pole voltage testing of electrical equipment and systems wiring and grounding to reduce power quality issues and avoid safety hazards. The meter is small and lightweight, with shock-resistant case material and taut-band movement. The OK light verifies proper connection between auxiliary earth resistance and lead wire connection to terminals. The tester warns the user when the resistance of auxiliary earth spikes exceeds tolerance. Ground-resistance meters are used by electricians and contractors working in industrial, utility, and field servicing.

Kyoritsu 4102A-H Earth Tester Features:

• The latest circuit design permits the instrument to operate
with the minimum of influence from earth voltage
and earth resistance of auxiliary earth spikes.
• Dust and drip proof. (designed to IEC 529 IP54)
• Earth resistance value can be read directly from the scale.
• Designed to meet IEC 61010-1 safety standard.
• Capable of measuring earth voltage.
• Small and lightweight. Shock resistant new case material.
• 2mA measuring current permits earth resistance tests
without tripping earth leakage current breakers
in the circuit under test.
• Lead wire connection to C and P terminals and proper
auxiliary earth resistance can be checked by “OK” lamp.
Lead wire connection to C and E terminals is good
when “OK” lamp is illuminated.
• Hard Carry Case

The Kyoritsu 4102A Earth Tester is capable of testing earth resistance up to 1200Ω. This can be achieved via the 2 pole or 3 pole method with the supplied accessories.

The Kyoritsu 4102A Earth Tester is designed so 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 Kyoritsu 4102A Earth Tester also has the ability to measure earth voltage, up to 30V AC.

Small and lightweight, the Kyoritsu 4102A Earth Tester is both dust and drip proof, conforming to the IP54 standard. The instrument is also shock resistant and designed to meet IEC 61010-1 safety standard. The Kyoritsu 4102A-H Earth Tester is supplied with earth resistance test leads, measurement probe, auxiliary spike kit, batteries, a shoulder strap and a hard carry case.
