Description

The AEMC Model 6424 is a professional, multifunctional digital ground resistance and continuity tester engineered for fast, accurate verification of grounding electrodes, earthing grids, and equipotential bonding across commercial, industrial, and electrical utility installations. Capable of performing 2-Point low-resistance continuity, 3-Point Fall-of-Potential ground resistance measurements, and live electrical potential diagnostics, the instrument covers an earth resistance span from 0.50 Ω up to 2000 Ω with full autoranging. Utilizing advanced synchronous demodulation filtering running at 128 Hz or 256 Hz, the Model 6424 rejects 50/60 Hz stray industrial ground currents, harmonic interference, and DC earth potentials, guaranteeing repeatable and stable measurement results in active, high-noise electrical distribution networks. Engineered with advanced productivity features, the Model 6424 simplifies the IEEE 81 62% Fall-of-Potential validation method through dedicated 52%, 62%, and 72% push buttons. Technicians can measure, store, and display all three test positions simultaneously on screen, with the unit automatically calculating and displaying the percentage deviation to instantly validate measurement accuracy without manual calculations. Beyond resistance testing, the tester measures AC/DC ground voltage up to 600 V and leakage current from 0.5 mA up to 60 A (via optional current probes), enabling live safety verification before executing resistance tests. An intuitive color-coded terminal layout (Green for E/Earth, Blue for ES/S Potential, and Red for H Current) prevents hookup errors, while intelligent on-screen indicators warn operators of high auxiliary rod resistance (RH and RS) or excessive stray interference voltages. Constructed for severe outdoor utility duties and continuous mechanical durability, the Model 6424 is housed in a rugged, shock-absorbing thermoplastic enclosure rated IP65 for complete dust-tight performance and water-jet resistance. The high-contrast, dual-display digital LCD screen incorporates bright backlighting and an analog-style bargraph for intuitive trend tracking in dark electrical vaults or direct sunlight. Powered by six rechargeable NiMH AA batteries with an integrated internal charger (operating via USB or AC power packs) or standard 1.5 V AA alkaline batteries, the tester provides up to 2,000 measurements per charge. Certified to strict international safety standard IEC/EN 61010-1 rated at 600 V CAT IV, the AEMC 6424 provides certified operator overvoltage protection across primary service entrances, industrial machinery, and lightning protection down-conductor grids.
