Microcontroller Course 1; Lesson 8; Digital Voltmeter

The digital voltmeter is an optional purchase for this course. This tool allows the student to measure voltages, currents and resistance. This lesson covers the basic functions of the DVM and the do’s and don’ts of using it. Knowledge Check What does the solid line over the dashed line represent on the DVM? When using the voltage range, what range of voltages can be measured when set to the 20m range? When measuring resistance, what range of resistances can be read on the 20M range? When measuring current, describe how to connect the DVM to the circuit. What precaution should you take in measuring resistance?
