【Four Techniques to Efficiently Use a Digital Multimeter】 1. Determine if a Circuit or Device is Live The AC voltage range of a digital multimeter is very sensitive; it can display even small induced voltages. Based on this feature, it can be used as a test pencil. The method is as follows: set the multimeter … Read more
A multimeter, also known as a multimeter, three-use meter, or multifunction meter, is a versatile measuring instrument that can measure direct current (DC) current, direct voltage, alternating voltage, resistance, audio levels, and more. Some models can also measure AC current, capacitance, inductance, and certain parameters of semiconductors (such as β). Measuring AC voltage: As shown … Read more
The measurement process of a digital multimeter involves converting the measured value into a direct current voltage signal through a conversion circuit, then converting the analog voltage into a digital quantity via an analog-to-digital (A/D) converter. The result is then counted by an electronic counter and displayed directly on the screen as a digital readout. … Read more
The multimeter distinguishes between live and neutral wires. Pointer Multimeter Distinguishes Live and Neutral Wires (1) Contact Measurement Method Set the multimeter switch to AC 250V or 500V. Connect the first probe to one end of the power supply and the second probe to ground (for example, on a water pipe, radiator, or damp ground). … Read more
