UPGRADED PROFESSIONAL GROUND TESTER - Uses mutual induction to detect traditional-method-undetectable ground faults. For grounded loop systems, the earth resistance tester needs no grounding lead disconnection or auxiliary electrodes; safe, fast, easy to use.
CONVENIENT & EFFICIENT - Resistance measurement range of 0.010 to 395Ω, with a 55mm×32mm clamp opening, suitable for measuring most flat grounding conductors. 4-digit LCD display provides higher resolution and accuracy, reducing the need to switch measurement ranges.
HIGH ACCURACY - Grounding loop tester with self-check, clock and alarm functions (1Ω and 10Ω test loops ensure accuracy). Widely used to measure ground resistance in telecom, power, meteorology, data centers, oil fields, power lines, towers, gas stations, factories, lightning rods, etc.
USB DATA TRANSFER - Can store 500 sets of data and export data via a USB cable to upload to your computer for storage and printing. A flashing ‘MEM' symbol indicates that the storage space is full, prompting users to take timely action to ensure test continuity and improve work efficiency.
PACKAGING - Comes with internal resistance tester, 1 x test loop, 1 x protective case, manual, 4 x battery, 1 x USB communication cable. Before measurement, the standard test loop can be used to verify the accuracy of the device, suitable for various scenarios.
