    Description

    Ground Resistance Tester Calibrator Lightning Protection Standard Resistance
    ETCR3900  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 1m
