Chauvin Arnoux MN14 [P01120416]  0.5 - 240 A AC Clamp Meter Adapter. These ergonomic mini-clamps are designed to make light work of measuring low and medium currents from 0.01 A to 240 A AC. The shape of the jaws makes ‘hooking’ onto cables easy, even in areas of restrictive access. The jaws can grip conductors up to 20 mm in diameter. Depending on the particular model, they have one or two calibres. The output is via either jack sockets or a lead with 4 mm Ø plugs, hence these clamps are compatible with all multimeters and testers on the market. There are two types of MN series clamps available. The fi rst kind operates as a current transformer (ratio 1,000/1) and gives a current output (mA) for use with any tester with current calibres. The second type gives a voltage output (DC or AC depending on the model) proportional to the measured current (1, 10, 100 or 1,000 mV/A). This voltage output means that, even with testers without any current calibres, it is possible to measure currents by means of the DC or AC voltage calibres. There are specifi c models in the MN series that have been designed with particular applications in mind such as measurement on current transformer outputs, on oscilloscopes and even of leakage currents.
