A digital multimeter is the handiest tool for an electronics engineer, and to be successful in the industry, it is essential to be well versed in the functioning and usage of this tool. A digital multimeter is a lightweight, battery-operated device that can be used for measuring a variety of electrical values in a circuit, namely, voltage, current, and resistance. It also comes into use for testing diodes and measuring the continuity of a complex circuit, thereby making it an essential tool for the manufacturing, testing and repairing of electronic circuits.
This slide deck provides a comprehensive overview of the usage of a multimeter for its various purposes.
Now your multimeter is ready to measure the property of resistance.
Tip – Always check what unit of resistance does the displayed value correspond to. The values may be in displayed in Ohms, Kilo Ohms, and Mega Ohms. For an accurate reading, select the appropriate range of resistance by turning the knob on the multimeter. e.g If you know that the resistance value falls in the range of 200-250 Ohms then point the knob to the 200 Ohm or 2 Kilo Ohms range.
