Difference between Analog Digital Multimeter | Digital Multimeter 2020

A multimeter is such types of device which is used to measure many types of electrical circuits such as current, voltage, resistance, inductance, capacitance, and electrical frequency.

The most important difference between an analog multimeter and the digital multimeter is that

the analog multimeter includes a scale and a deflection pointer which actually specifies the value to be measured on the scale,

while, in digital multimeters, a digital display like LCD directly displays the value.

Pros Tips:

Digital Multimeter has good quality on the basis of certain factors like high accuracy, easy for reading calibration, cost,

advanced functions of troubleshooting, TRMS Technology, construction, supply source, input signals, and noise.

What is the Main difference between analog digital multi-meter?

 

The following table keys out the main differences between Analog and Digital Multimeter.

 

CharacteristicsAnalog MultimeterDigital Multimeter
AccuracyProne to error because of wrong pointer based readingMeasures with great accuracy
ReadingProvides reading on a scale against pointerProvides reading in numeric form appeared on a LCD
CalibrationCalibration is done manuallyThey are calibrated automatically before taking any measurement
CostLess costly as they offer very few featuresExpensive as they offer a wide range of features
RangeHave to set a range of measurement manuallyMostly, they have auto-ranging feature but costlier than their counter-parts
Measuring parametersUsually it measures current, voltage, and resistanceMeasures current, voltage, resistance, capacitance, and inductance as well
ADC RequirementDoes not require analog-to-digital converter (ADC) to display readingRequires ADC in order to display the reading on LCD
AC FrequencyHighest AC Frequency which can be measured is lowerThe highest AC Frequency which can be measured is higher than its counterpart
ConstructionConstruction is easy and simpleComplicated construction because of several electronic and logic components involvement
Power supplyIs not requiredIs required in these types of meters
SizeBigger in sizeVery small like hand-held devices
NoiseSuffer less from electric noiseSuffer more from electric noise
Input signalsDisplays only one input signal valueIt is able to accept multiple inputs and has adjustable displays which allow user to choose between the input signals
