Description: Ground Resistance Tester Calibrator Lightning Protection Standard Resistance exclusive use of lightning protection standard resistance for lightning protection consists of 9 1 / 2W high-precision military-grade wire-wound resistors. When the resistor is calibrated, the gear shift test is performed directly without the need to replace the test wire. The stable performance and sturdy structure make the calibration test particularly convenient. The military-grade wire-wound resistors used have the highest accuracy of 0.05%, and their resistance values include 1mΩ, 10mΩ, 100mΩ, 1Ω, 10Ω, 100Ω, 1KΩ, and 100KΩ. They fully meet the requirements of National Meteorological Administration Order 31 [Lightning Protection Device Testing Qualification Management Measures] 10-3 ～ 105Ω range. This standard resistance is mainly used for calibration of ground resistance tester, equipotential tester and other instruments. Widely used in building quality inspection stations, supervision companies, construction units, lightning protection companies, power departments, etc. Product Characteristics 1.
