Kyoritsu 4105A-H Earth Tester – Hard Case Model
The Kyoritsu 4105A-H digital 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 4105A-H Earth Tester test the condition of a grounding system, and provide resistivity measurements in ohms. Grounding systems protect people and equipment, and provide a safe path for the dissipation of fault currents, lightning strikes, static discharges, EMI and RFI signals, and interference. Regular testing of a grounding system is important for safety and protection of equipment. For example, corrosive soil with high moisture content can degrade ground rods and connections in existing systems and increase the resistance of the system. Ground-resistance meters are used in conjunction with a variety of testing methods to troubleshoot intermittent electrical problems or as part of a regular maintenance plan.
Kyoritsu 4105A-H Earth Tester Features:
• Dust and drip proof.(designed to IEC 60529 IP54)
• In addition to the facility for precision measurement, test leads for simplified two wire easuring system also supplied as standard accessories.
(unit can be hung from the neck for simplified measurement)
• Designed to meet IEC 61010-1 safety standard.
• Capable of measuring earth voltage.
• Automatic warning when resistance of auxiliary earth spikes is in excess of tolerance.
• 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.
