ที่ Standard Resistor for Lightning Protection 1009015 is a high-performance calibration device designed for grounding resistance testers, equipotential testers, and similar instruments. It features manual range operation, military-grade wire-wound resistors, and supports direct range switching without changing test wires, ensuring stable performance and robust structure.
This resistor offers a comprehensive range of specifications: 0.001Ω (2%), 0.01Ω (0.5%), 0.1Ω (0.2%), 1.0Ω (0.2%), 10Ω (0.05%), 100Ω (0.05%), 1KΩ (0.05%), 10KΩ (0.05%), and 100KΩ (0.05%), meeting diverse calibration needs. It adopts a 4-wire connection method for high accuracy, with a power rating of 1/2W and a temperature coefficient of ±25ppm, ensuring reliability across environments.
Housed in a durable casing (173mm×125mm×70mm, 360g), it comes with red and black 0.5m test wires (2 each). It operates in -10℃~40℃ (≤70%rh) and stores in -20℃~60℃ (≤80%rh), with insulation resistance ≥10MΩ (500V) and AC 3700V/rms withstand voltage. Compliant with IEC61010-1, CAT III 600V, and JJG166-1993, it’s ideal for calibration labs, lightning protection engineering, and military applications, delivering consistent performance for precise instrument calibration.
