Search on WeChatTechnical Training First, it is important to clarify that if the sensor is already broken, it is meaningless to short-circuit it! The sensor, as the first line of defense for measuring input, converts the measured variable into a measurable signal, which can be an analog signal, a digital signal, or other forms of … Read more
The digital multimeter is a powerful assistant for measuring electrical signals. Although it is called a “universal” meter, its common functions are limited to measuring voltage, current, and resistance. Voltage and current measurements also include AC and DC ranges. In addition, some multimeters can measure inductance, capacitance, continuity, diode forward voltage, transistor current gain, counting … Read more
