AC Current Probe Model MN251

The MN251 is a general purpose AC current probe with voltage output. It is designed for use with DMMs or with measuring instruments with voltage inputs. These probes permit the measurement or recording of current with instruments without current ranges. The voltage output is proportional to the current measured (through the jaws). The MN251 offers a voltage output of 1mV per Amp measured. The MN251 has integral 5 ft (1.5m) leads terminated by shrouded banana plugs.
