DLRO tests), direction of rotation plus supply phase rotation tests.
All these new test abilities go together to make the IMT100 a real world, versatile, hand held test instrument for
rotating machinery.
The IMT100 also comes in an over-moulded case, providing increased protection, robustness and achieving an IP54
