Abstract

Ein Multimeter, vorzugsweise mit elektronischem Überstromschutz, ist mit Messkreisen für Strom, Spannung und Widerstand und mit zwei Messleitungen versehen, welche über einen Eingangswiderstand mit einer Steuer- und Auswerteschaltung verbunden sind, die einen Spannungsteiler und eine Hochspannungs-Generatoranordnung mit Regelkreis aufweist. Um bei einfacher Bedienung eine erhöhte Flexibilität und Sicherheit zu bieten, ist die negative Prüfleitung über einen Messwiderstand mit der Masse verbunden und sind parallel sowohl eine Spannungsmessanordnung in Verbindung mit dem Spannungsteiler als auch eine Strommessanordnung in Verbindung mit dem Messwiderstand vorgesehen.A multimeter, preferably with electronic overcurrent protection, is provided with measuring circuits for current, voltage and resistance and with two measuring lines, which are connected via an input resistor to a control and evaluation circuit having a voltage divider and a high-voltage generator arrangement with control loop. In order to provide increased flexibility and safety with simple operation, the negative test lead is connected to ground via a measuring resistor and a voltage measuring arrangement in connection with the voltage divider and a current measuring arrangement in parallel with the measuring resistor are provided in parallel.
