The Testboy TV 430 is a digital insulation measuring instrument that makes it possible to check the insulation resistance of devices, electrical systems and circuits with three selectable test voltages 250, 500 and 1000V DC. A continuity tester andan AC voltmeter have also been integrated to round off the options for use in a wide variety of applications. The most important aspect when measuring insulation resistance is the elimination of the effects of any capacitance. This is achieved by measuring with DC voltage. In order to achieve a meaningful result, the test voltages and the test current are defined so that the influence of the current- or voltage-dependent resistances remain the same. During the original inspection, the measurement of the insulation resistance must be carried out between each active cable and earth.
