Top 16 Difference between Analog and Digital Multimeter

Electrical and Electronics Engineering feature image

Multimeter is a popular type of handheld electrical measuring instrument.

Like its name as multimeter, it works as an ammeter, voltmeter, and ohmmeter to measure currentvoltage, and resistance respectively. It is also called Ampere-Volt-Ohm (AVO) meter or Volt-Ohm-Milliammeter (VOM).

There are the two types of multimeter.

  1. Analog type multimeter
  2. Digital type multimeter

These two classified multimeters are capable of measuring and displaying accurate reading in different ways. Also, both are used for different purposes as they come up with different specifications.

In this tutorial, we are going to study what is the difference between analog and digital multimeter.

Difference between Analog and Digital Multimeter

Let’s compare the analog and digital multimeter in tubular form.

01What is the analog & digital mutlimeter?The multimeter having the ability to measure electrical quantities and to display their reading on the scale by moving the pointer is called Analog Multimeter.The multimeter having the ability to measure electrical quantities and to display their reading on screen by the numerical value is called Digital Multimeter.
02SynonymsSometimes, the Analog multimeter is called AMM or Analogous multimeter.Digital multimeter is also called DMM or DVOM.
03Representation of measuring signalThis instrument shows a continuous signal.This instrument shows the discrete signal.
04Size of multimetersThe analog multimeter occurs in a large size as compared to the digital multimeter.The digital multimeter occurs in a small or pocket size.
05Reading display In an analog multimeter, the reading displays on the reading scale (like vacuum fluorescent).In a digital multimeter, the reading displays on the digital (like LED or LCD) screen.
06CalibrationThis multimeter has the ability to provide manual calibration.This multimeter has the ability to provide automatic calibration.
07Measurement
accuracy
In the case of measurement, it gives less accuracy.It gives more accuracy as compared to the analog multimeter.
08CostAnalog multimeter can easily get at low cost. Digital multimeter is very costly.
09Output readibility It indicates the approximate or less accurate reading due to pointer moves over the calibration scale.It indicates accurate reading due to the numerical value.
10Nature of the signal in multimeterThe moving pointer or needle gives a continuous movement in order of magnitude for momently changes of the signal.This does not give a continuous movement in order of magnitude.
11Polarity
function of a both multimeter.
In an analog multimeter, the positive and negative polarities are represented by using the right and left sides of pointer deflection respectively. In a digital multimeter, the positive and negative polarities are represented by using the positive and negative signs respectively.
12Auto-polarity functionIt does not have an auto-polarity function. It requires the test leads and probes to detect the polarities. It has an auto-polarity function.
13SensitiveThis is a very sensitive type of instrument.This is not much sensitive type of instrument.
14OperationIt is not easy to handle as compared to the digital multimeter.It is very easy to handle.
15Speed of operationAnalog multimeter has a lower speed.Digital multimeter has a higher speed.
16ErrorThis instrument contains a number of different scales. Thus, the user can be confused to find out accurately measured units.
They were often a cause of the error.
The user gets an accurate reading in numerical form. Thus, there is not much error in a digital instrument.

These 16 points have covered the difference between analog and digital multimeter. And this difference describes the advantages and disadvantages of an analog and digital multimeter.

Multimeter Uses

These types of instruments are widely used in-

  • electrical circuit lab for testing circuits,
  • troubleshooting a communication circuit,
  • electrical project lab,
  • maintaining and performing many kinds of tasks in outdoor fields like a substation.

These are the basic applications in daily life. Mostly linemen or technicians already know the importance and benefits of having a multimeter tool.

  1. Analog multimeter- They gives numerical values and their is gross errors.

    Digital multimeter- They gives value in digital numerical (Accurate) and in this meter no gross errors.
