Analog vs Digital Multimeter

Don’t be confused due to the variety of multimeters available in the market. To have the right meter at the right place at the right time requires research and planning. The main two categories are the digital multimeter and the analog multimeter. Depending on the project or job category you just need to pick the right one to make your life easy. The meter is specified as “Multi” as it provides multiple readings in a single unit. You might see digital multimeters are everywhere still analog or manual multimeters can provide a variety of different benefits. We will be discussing the benefits and also the drawbacks of both below.

Benefits of Digital multimeter

More functionality

Technology is upgrading so rapidly. Functionality is a very big issue if you are dealing with varieties of electronics product. Digital multimeters can give you the freedom to measure lots of parameters. Competency is a huge advantage of it over analogs.

User-friendly

These meters are very much portable although it contains many functionalities. The meters more often comes with buttons to easily operate.

High input impedance

They have a very high input impedance. On the other hand, analog multimeters have very low input impedance. Which causes lower sensitivity. So the calibration of voltage sometimes become complex for analog multimeters.

Other benefits

  • No zero adjustment required
  • The digital output can be further processed for other application
  • Can store the values of the reading and use help by saving time.

No chance of parallax error

As the meter provides LCD numeric value display there is no parallax error. The pointer of an analog multimeter viewed from a different angle causes this type of error.

Benefits of Analog multimeter

Better Readout

Analog clearly gives a better visibility of changing trend of a parameter in a circuitry. While digital multimeters give you digital values, analog mm provides a better experience of changing trend.

More accuracy

Analog ones give more accuracy than digital ones. Digital multimeters may not provide absolutely accurate result all the time.

Some practical examples

Suppose all loads are removed from a circuit also the house circuit breaker is switched off. Still, a digital multimeter will give a voltage reading. This voltage reading is from the load side of the circuit. This fault is caused due to the input impedance present in the circuit. The analog multimeters exclude such error.

Final Verdict

A multimeter is said to be an electronics designer’s primary testing tool. Not necessarily you are an engineer, every day you are using lots of gadgets that may require troubleshooting or modification. It may be a small electronic circuit or maybe a large complicated circuit tasting the component can save you a lot. It can navigate you through the root problem.

Checking the compatibility and choosing the right multimeter is all it takes to sort out the problem. If you liked this content please share it in your social media profiles and let your friends benefit from it.
