摘要： A fan speed testing system includes a voltage regulating module, a rotational frequency collecting module, and a rotational frequency converting module. The voltage regulating module receives an AC voltage signal and converts the AC voltage signal to a variable first DC voltage signal to adjust a rotational speed of a fan. The rotational frequency collecting module detects the rotational speed of the fan and outputs rotational frequency signals. The rotational frequency converting module receives the rotational frequency signals and determines the rotational speed of the fan according to numbers and period of time level voltage switching in the rotational frequency signals.

摘要： A thermocouple welding test apparatus for testing whether a thermocouple is normally welded includes a first comparison circuit, a second comparison circuit, a switch circuit and an indication circuit. The first comparison circuit receives a first DC voltage from the thermocouple, and compares the first DC voltage with a first reference voltage to output a first control signal. The second comparison circuit receives a second DC voltage from the thermocouple, and compares the second DC voltage with a second reference voltage to output a second control signal. The switch circuit receives the first control signal and the second control signal, and outputs an indication signal accordingly. The indication circuit receives the indication signal, and indicates whether the thermocouple is normally welded accordingly.
