AEMC 6470-B Multi-Function Digital Ground Resistance Tester Kit, 99.99 Kilohms Resistance, 32V Voltage, 250mA Current with 300' Leads

The AEMC 6470-B multi-function digital ground resistance tester with 300-foot leads performs 3-point ground resistance, 4-point soil resistivity, and 2- and 4-wire bonding resistance testing in rugged conditions, such as field maintenance with numerous tests. The tester is designed for ease of use with “connect–press–read” operation, a large easy-to-read LCD screen, and user alerts. For higher accuracy in electrically noisy environments, the tester can be operated in manual or automatic frequency scan mode from 40 to 513Hz. Test voltage of 16V or 32V can be selected up to 250 milliAmp (mA) test current. The tester automatically recognizes all electrode connections and their resistance value. The auto power-off feature turns off the tester after a set period for power management. Ground-resistance meters are used by electricians and contractors working in industrial, utility, and field servicing.

The tester’s software (included) is compatible with Microsoft Windows XP, Windows Vista, Windows 7, and Windows 8. It enables remote set-up and operation of all measurements, and provides data storage, real-time display, analysis, report generation, and system configuration. Up to 512 complete test results can be stored in memory for recording data in the field and then analyzing readings when convenient. After taking measurements, reports are automatically generated.

The AEMC 6470-B exceeds IEC mechanical and safety specifications for shock, vibration, and drop tests. The double-insulated tester is compliant with grounding standards IEC 61557 parts 4 and 5. Safety ratings include EN 61010-1, CAT IV 50V, and pollution degree 2. The tester kit includes two 300ft. color-coded leads on spools (one red, one blue), two hand-tied 100ft. leads (one green, one black), two 5 ft. leads (one red, one blue), four 14.5" T-shaped auxiliary ground electrodes, five spaded lugs, 100ft. tape measure, DataView software, rechargeable NiMH batteries, optical USB cable, 110/240V power adapter with 115V U.S. power cord, ground testing workbook and DVD, carrying bag, and user manual. When closed, the carrying case has an IP 54 rating that protects the instrument from dust and water.

H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.

Ground-resistance meters test the condition of a grounding system, and provide resistivity measurements in ohms. The meters are available in digital, analog, and clamp models. 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.

AEMC Instruments manufactures electrical testing and measurement instruments, including clamp meters, power quality analyzers, ground resistance testers, and data loggers. The company, founded in 1893, is headquartered in Foxborough, MA.
