The METRAVO 4 D is a digitally indicating multimeter featuring liquid crystal display. It offers a plurality of applications in the field of electronics, e.g. in research and development, in production, operation, test rooms and service. It features a constant input resistance of 10 MO 100 pF on all voltage measuring ranges. On 26 measuring ranges, it measures DC and AC voltages up to 650 V, DC and AC currents up to 10 A (temporarily up to 20 A), and resistances up to 20 MQ. Several well-tuned protective means protect the instrument against damage through improper handling and overload: — Overdimensioned precision resistors — Melting fuse in conjunction with protective power diodes — Overvoltage arrester. The rugged design of the METRAVO 4 D, particularly in conjunction with the rubber bag, assures extreme protec- • • tion in case of rough mechanical application. The METRAVO 4 D is fitted with a liquid crystal display i » * (LCD), the high contrast of which is also maintained in environments of very bright light. The instrument operates mains-independent on commercially available Mignon cells. Thanks to the electronic components in LSI technique and the liquid crystal display, current consumption is extraordinarily low so that a long life of a set of batteries is assured. 5 The measuring instrument is constructed to comply with the safety rules of VDE0411 and, if handled with care, assures protection against hazards of electric shocks which is required by VDE 0110 and DIN 40 050.
