Difference Between Analog and Digital Multimeter

Hello guys, I hope you all are doing great. In today’s tutorial, we will have a look at Difference Between Analog and Digital Multimeter. The multimeter is an electronic device that used to measure different quantities like voltage, current, resistance. There are 2 main types of multimeter first is analog and second is a digital multimeter. The main difference among them is their way by which they show output.

The analog meter shows calculated values through analog way by showing the position of a pointer on the scale. While digital meter shows the measured values in the form of numbers on the screen. In today’s post, we will have a detailed look at both meters features and compare them to find their related differences. So let’s get started with Difference Between Analog and Digital Multimeter.

Difference Between Analog and Digital Multimeter

Analog Multimeter

This displays the calculated values through the deflection of the pointer.
In this meter, an analog to digital converter does not exist.
It used to finds the values of different electrical terms lie volts, current frequency.
Its main component includes the function of volts, resistance, and ampere.
It helps to solve electronic and electrical faults
The latest meter helps to measure capacitor diode testing

The output accuracy is less for this meter..
It causes less noise.
During operation, it gets only one input signal.
Its price is less.
Its physical area is larger.
It is difficult to use.
It calibrated through the manual way.
It comes with DC volts, ac volts, DC, and different decibel calculations
The analog meter used to measure current has a clamp for the connection
During buying the meter its measuring value must be checked
ts main features are battery, overload protection, and mirror scale
It has overload protection with fuses.
It has mirrored scale that used to measure temperature values.

It comes with a bench top. That used to handle and wheels.
Its input resistance values can be varied according to the range
To the operation of the analog meter, there is no need of a power source. The power source is only needed when resistance is measured.
Its circuit configuration is simple as compared to the digital meter.
The frequency range for this meter is two kilohertz.
Analog meters find the values of voltage, current, and resistance.

Digital Multimeter

The output of the meter is shown in the form of digits.
It used to measure the 2 or more than 2 electrical terms like volts resistance and current
It mostly employed in industries

It requires an analog to digital converter to show values.
It has four main parts display buttons dial and input jack
Its accuracy in the calculation as compared to the analog meter is large.
Its size is less than the analog meter.
Its price is high.
It can be easily used than the analog meter.
Its input remains constant for all ranges.
It causes high noise.
It needed a power source for operation.
Its circuit is complicated than analog meter due use of ADC, LCD.
This meter can also measure current voltage, resistance, impedance, and can test the diode and transistor.

Analog Multimeter vs Digital Multimeter

Analog Multimeter

The analog multimeter is used to perform different electrical quantities measuring and give values through deflection of the pointer on the scale.
AMM is the short form of an analog multimeter.
The analog meter comes with a permanent magnet moving coil galvanometer. There is a pointer used with the moving coil. The pointer deflects on the scale for showing readings.
• The analog meter has a rotating knob for choosing the range.
In this meter, the pointer deflects the left side to show reverse polarity.
The analog meter is not a power supply for voltage and current measuring, but it is needed to use for resistance measurement.
It has a low frequency range and is less susceptible to electric noise.
It is a larger-sized and low-cost meter.
The analog meter measures electrical parameters like voltage, current, and resistance. The analog meter shows a reading through the deflection of the pointer on the scale.
It is not needed an analog to digital converter.
It can be calibrated manually.
It is difficult to use. Its input resistance is variable and varies with change in range.
Analog meters are less accurate as compared to digital meters. Since of wrong pointer reading and parallax error.

Digital Multimeter

The digital meter is a multipurpose electronic device that is used for measuring current, capacitance, resistance, voltage, and other parameters and gives output in digital form.
The digital meter comes with different circuits like encoders, a logic controller, an ADC, and a digital display that are connected in one unit for measuring and providing different quantities in digital form.
The DMM is a short form of digital meter.
Different DMMs are used for measuring current, resistance, voltage, inductance, and capacitance. It also tests diodes and transistors.
Automatic calibration is done with digital meters.
Digital meters give readings on a digital display in the form of digits. It uses ADC for showing results.
It is easy to use and has constant input resistance for different ranges.
It is a highly accurate meter and also has auto-ranging features.
It shows a negative value for reverse polarity.
It needed a power supply for starting and performing different measurements.
Its permissible frequency range is higher and more susceptible to electric noise.
It is a smaller size than an analog meter but at a higher cost.
