Abstract

PURPOSE: To enable a measurement test with high accuracy in a short time by a method wherein a display of a unit lower than the minimum display unit is displayed by a flickering display by installing an auxiliary indicator.
CONSTITUTION: An output of a voltage converter 1 is multiplied by an output of a current converter 2 and an output current proportional to an input current is obtained and its is supplied to an integrator 4 to be converted into a frequency signal. This frequency signal is divided into 1/N through a unit 21 and this divided frequency is once more divided into 1/10 through a unit 22 to drive a pulse motor 7 and further, an electric power is displayed in a mechanical type accomulating displayer 8. And further, an auxiliary indicator 23 such as LED, etc. is made to flicker by the 1/10 divided frequency. As a result thereof, a signal having an operation frequency 10 times as many as that of the pulse motor 7 is applied to the LED 23 and by means of 10 times of a flickering operation, one grade of the minimum display unit of an indicator 8 is incremented.
