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.
The different specific resistances are specified by selecting one of the pre-programmed materials, or by measuring the specific resistance of unknown materials and entering the result. Preferably the coat thickness is displayed, but the measurement and display of the actual resistance, the square resistance and the specific resistance is possible, too. All measured values can be transmitted into a PC via a serial interface. Controlling the MR-1 on the other hand is not possible.
