The MRC 100S-BD-3 Bounding Tester is a battery-powered portable digital ohmmeter, which can be used, for example, for testing the ground connection in any section of an aircraft using different measuring currents (up to 10A). This high current ensures that any uncertain connections are recognised.
该MRC 100-BD-3边界测试仪是一种电池供电的便携式数字欧姆计，例如，可用于测试地面连接在飞机的任何部分使用不同的测量电流(高达10A)。这种大电流确保任何不确定的连接都被识别出来。
