SAFETY FEATURES AND PRECAUTIONS You have selected an instrument which provides you with a high level of safety. The multime- ter is manufactured and tested in accordance with safety regulations IEC 61010–1 / DIN EN 61010–1 / VDE 0411–1. When used for its intended purpose, safety of the operator, as well as that of the instrument, is assured. -
Page 4: Description
DESCRIPTION The MI7054 multimeter has been designed for measurements in industry, for training and in the commercial trades. Its greatest advantage is protection: The current measuring ranges are protected against overload with an electromagnetic protective relay (AUTO-FUSE), resistance ranges are protected with a PTC thermistor, and the voltage measuring ranges are protected through the use of adequately dimensioned electrical components. -
