Small, compact and very tough, the model MN103 is designed for measurements from 1mA to 100AAC. The "clothes pin" shape makes it ideal for use in tight areas, such as breaker panels, controller panels or outlets. It is an excellent companion to all DMMs. The model MN103 provides a voltage output proportional to measured current (1mV/mA and 1mV/A). This voltage output enables instruments with AC voltage ranges to measure, display or log currents. The model MN103 permits true RMS measurements when used with a true RMS instrument. The model MN103 permits very low AC current measurements. Features: small, compact and very tough AC probes. "Clothes pin" shape makes them, ideal for use in tight areas, such as breaker panels, controller panels, or outlets.
