Advantages of digital meters over analog meters

  1. 1. ADVANTAGES OF DIGITAL METERS OVER ANALOG METERS
  2. 2. ANALOG AND DIGITAL METERS. ANALOG METERS: An instrument which measures and indicates values by means of a continuous scale within which any value may be specified. Most of the time a pointer is used to indicate readings. DIGITAL METERS: A digital meter is a device used by technicians to test and measure electronic circuits. Most of them are portable, battery-powered units. They show measurements as numbers and symbols on an electronic display.
  3. 3. WHY ANALOG WAS REPLACED BY DIGITAL METERS? 1. Accuracy. 2. Robustness. 3. It has moving parts. These can get affected by an accidental drop to floor. 4. It has relatively less input resistance especially in low voltage ranges such as 3V prone to parallax error.
  4. 4. PARALLAX ERROR.
  5. 5. ADVANTAGES OF DIGITAL METERS 1. Output Display It is easy to gauge a reading through digital multi-meter since the output is automatically displayed in numbers through a Seven Segment Display. 2. Accuracy A digital meter takes a precise, computer-generated reading and displays it on the screen.
  6. 6. 3. Auto Polarity Placing the probes into the opposite polarity will result into a negative output. 4. Stable Calibration We should only have to calibrate our digital meter once -- when you first turn it on. 5. Current Protection Most digital meters feature protection from sudden shifts in current.
  7. 7. 6. Precision. 7. It can hold the reading in memory . 8. The reading speed is increased as it is easier to read. 9. With the advent of Integrated circuits, the size, cost and power requirements of digital multimeters has been drastically reduced.
  8. 8. 10. No moving parts, life will be high. 11. Has high resolution: Can detect very small changes of the order of 0.1% of range. 12.User friendly. A digital meter performs the calculation and displays the reading. 13. Portable size makes it easy to carry anywhere.
