Abstract

PURPOSE: To achieve the higher efficiency of measurement, the miniaturization of the device and the reduction of its cost by detecting a slight voltage change of change rate by the use of a Zener diode.
CONSTITUTION: When the specified voltage to be changed by a select switch 1 is applied to a Zener diode 3 and a load resistance 4, the voltage component above the Zener voltage is applied across the resistance 4. Hence, the voltage across the resistance 4 is measured with a voltmeter 5.
