AC Current Probe Model MN291

The MN291 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 MN291 offers a VDC output of 100mVDC per AAC and may be used with loggers or other instruments with DC voltage input. The MN291 has integral 5 ft (1.5m) leads terminated by shrouded banana plugs.
