Engineered for performance and durability, this advanced load tester is built to handle demanding shop environments. Featuring heavy-duty vinyl-coated steel “Flexi-Spring” clamps with 800 Amp copper jaws, it ensures secure connections every time. The easy-to-read LED voltmeter and ammeter provide clear monitoring of system performance, while max/min current and voltage tracking delivers precise diagnostics. A microprocessor-based control board, protected by a rugged conformal coating, safeguards against reverse connections, moisture, and dirt. For extended, high-duty cycle use, a microprocessor-controlled fan keeps the unit cool and reliable. Capable of testing both 12V and 24V electrical systems, it automatically adjusts as a 70‐500 Amp variable load tester. A detachable industrial inductive amp probe with a degaussing button adds versatility and precision for accurate current measurement. For added convenience, a silk-screened temperature compensation chart is located on the cabinet for quick reference, and the unit includes separate light-gauge, high-impedance test leads with alligator clips to easily access tight spots.
