Ohmmeter vs Multimeter – Which One Best!

There has been a long-running dispute between hordes of multimeter enthusiasts that has taken up a lot of Internet time lately. And all for the wrong reasons. The kerfuffle has brought to light that multimeters measure voltage, current, and resistance – a tidbit of information for those unfamiliar with the subject.

Generally, multimeters can be classified as Digital or Analogue, or Ohmmeters. People who are trying out these two subdivisions for the first time are facing a tremendous amount of hassle as they are on opposite sides of a fence. A person is often confronted with one rather peeved question before purchasing a multimeter:

Analog or Digital?

A digital multimeter is a voltmeter with a digital display that constantly flashes a value, whereas an analog multimeter or Ohmmeter has a steady scale on which an elongated needle indicates the measured value. A digital multimeter is the epitome of modern technology, while an ohmmeter is an older, more experienced device that is slightly off-the-shelf.

There are still quality ohmmeters available online from reputable brands such as Crown, Meco, and others! Both devices are great for measuring voltage, resistance, and current, but which one is best for prolonged use? We discover the truth!

1. Fluctuations in Electricity

An initial reading obtained by a digital multimeter may not be an accurate reflection of the current flowing through it, since the current can suddenly fluctuate at any time. An analog multimeter, on the other hand, accurately displays the sudden fluctuations that occur with the electrical flow, since it shows a constantly changing display!

In spite of the fact that the readings are not exactly the same as a digital multimeter, analog multimeters nonetheless provide a general reading of rapid fluctuations and ward off potential problems with the flow of electricity.

2. Scale of Multimeters

As analog multimeters come with a fluctuating scale, it is up to the user’s expertise and prudence to set the scale up properly and ensure the results obtained are valid. As a result, the scale is usually set incorrectly, which causes inaccurate readings. An analog multimeter, on the other hand, will automatically set the scale and display the readings.

3. Accuracy and Display

A digital multimeter displays measurements by flashing numeric digits on the screen, whereas an analog multimeter measures by engaging a needle that rests on a pivot against a printed background bearing numeric scales. Therefore, an analog meter has a high margin of error compared to a digital multimeter, which is quite accurate and can measure up to five decimal places.

 4. Price

In general, digital multimeters are much more luxurious than their analog counterparts. As a result, you can get a quality analog multimeter for a comparatively cheaper price than a quality digital multimeter.

Besides, analog multimeters come with a variety of options for displaying data, such as a galvanometer for recording movement, or a simulated pointer or bar graph! Besides providing a solid test rating, analog multimeters generally retain their value over time.

5. Change in Rate

The addition of a galvanometer to ohmmeters often makes them a better choice than digital multimeters when determining a measurement’s gradual rate of change. The fact is that despite all the ‘accuracy’ complaints and the ensuing cacophony, ohmmeters (though old) can measure with accuracy of up to 5%.

 6. Specifications

The humble ohmmeter simply can’t compete with digital multimeters on this front. Unlike other instruments, they can perform tasks beyond merely measuring current, voltage, and resistance. There are many types of digital multimeters available that can test light and humidity as well as sound. Therefore, it’s safe to say that they have outperformed the ohmmeter.

Ohmmeter vs Multimeter – Who wins?

Among digital multimeters, digital multimeters offer better readings and are easier to use. Nonetheless, analog multimeters and ohmmeters have their unique advantages and are definitely worth considering if you’re going for a cheaper solution to multi-metering.
