Abstract

PURPOSE: To obtain resistance value at reference temperature in digital value, by placing a resistance element and a resistor to be measured in the same atmosphere.
CONSTITUTION: The first constant-current circuit portion 1 lets constant currents flow through a resistor 2 to be measured, and the second constant-current circuit portion 7 lets constant currents flow through a resistance element 8 with the same temperature coefficient as the resistor 2 to be measured. An analog-digital converting circuit portion 3 works using voltage generated at the both ends of the resistance element 8 as reference voltage, detects resistance value from voltage at the both ends of the resistor 2 to be measured, converts the value into digital value and displays the value to a digital display portion 4.
