Abstract
A test apparatus for a thermal resistor includes a control device, a temperature processing circuit, a voltage regulating circuit and a temperature detecting circuit. The control device stores a plurality of predetermined voltage values and outputs control signals according to those predetermined values. The temperature processing circuit receives the control signals and outputs a pulse width modulation (PWM) signal according to the control signal. The voltage regulating circuit receives the PWM signal and outputs a first direct current (DC) voltage to heat the thermal resistor. The temperature detecting circuit detects temperature signals and current signals from the thermal resistor. The control device receives the temperature signals and current signals of the thermal resistor and generates a resistance-temperature graph of the thermal resistor.
