Abstract
PURPOSE: To perform a logarithmic conversion of the insulation resistance meter by using a simple configuration that consists of two diodes, a resistance and an indicator.
CONSTITUTION: A series circuit that consists of the high voltage power supply E, the diode D1 and the resistance r1 is connected between the measuring terminals 1, 2. Also another series circuit that consists of the indicator M, the resistance rs and the diode D2 is connected to both terminals of the diode D1. The sensitivity of the indicator M can be changed or its scale can be altered according to the purpose by putting a parallel or series circuit of plural diodes in place of the diodes D1, D2.
