Using a special 4-pole contact probe the MR-1 is Surface resistance meters used for the determination of a sufficient electromagnetic compatibility of metal-coated plastic cases. The MR-1 is small, easy to handle and is powered by a battery or an accumulator.
使用一种特殊的四极接触探头，MR-1是用于确定金属涂层塑料外壳的足够电磁兼容性的表面电阻计。MR-1体积小，易于操作，由电池或蓄电池供电.
