A digital multimeter is a test tool that is used to measure various electrical characteristics, including voltage, resistance, and current. The results are displayed via an LED display. This device is usually known as DMM and is often used due to its price, size, and ease of operation. With the help of a digital multimeter, you can measure:
- Voltage in alternating current and direct current circuits.
- Resistance of the entire circuit or across individual circuit components
- Current in direct current circuits and alternating current circuits.
A digital multimeter is widely used in:
- Troubleshooting a communication circuit
- Electrical project lab
- Electrical circuit lab for testing circuits
- Testing electrical outlets,
- Testing batteries
- Testing wall switches
- Testing extension cords
- Reading temperatures
- Maintaining and performing many outdoor tasks, including a substation
If you are choosing between a digital multimeter and an analog one, here is a list of the benefits of digital meters:
They Are Accurate
Digital multimeters are more accurate than analog ones. A digital meter can output up to four decimal places that the analog type of multimeter cannot show. The accuracy of a digital multimeter is around 1% or even less, while the accuracy of analog multimeters is no less than 3%.
Less Reading Errors
The quantity measured by a digital multimeter is displayed as a number. It eliminates parallax, observational, and approximation errors.
Effective And Simple Working Principle
Unlike other multimeter types, digital meters are known for their simple working principle. They are made up of the three basic elements:
- Numeric digital display
- Signal conditioning
- Analog-to-digital conversion
There Are Additional Measuring Functions
Most models of digital multimeters have additional features, such as a continuity buzzer and a diode test function. There are also the most modern models that have capacitor capacity and the measurement of frequency.
There are some digital multimeters that can test resistance up to 50 ohms with one ohms resolution. Some models can also be used a diode or measure transistor gain. There are also the most advanced models that are used for recording minimum and maximum values and can save the records through wireless internet.
Also, some trendy digital multimeters are armed with such picks as graphic illustration, low band instrumentation, surface mount technology, and others.
Auto And Manual Range Functions
The advanced models of digital meters have both auto range and manual range modes. The auto range mode allows a multimeter to choose the range with the best resolution. If it is the manual range mode, a user overrides auto range and chooses the range themselves.
They Are Portable And Durable
Since digital meters do not have any moving parts, they are free from wear and shock failures. They also have protection against undesired input ranges. In addition, digital multimeters are durable, long-lasting, and compact. Due to their portable size, you can take them anywhere. Also, if you use this type of meter by following the manual, there is no need for particular maintenance.
Auto Polarity And No Need For Zero Adjustment
Analog multimeters require zero adjustments, while digital meters do not. The auto polarity feature protects the multimeter when the polarity is reversed and shows polarity with a negative sign.
They Are Energy Saving
Most modern digital meters have energy-saving features. For example, there is the automatic power-off function: if a control key is not pressed within about 15 minutes, the multimeter is switched off automatically.
There Are Different Ranges
You can also measure quantities with different ranges. There is a knob that allows you to select various ranges of electrical characteristics. You can select all the available measuring modes manually. It is possible to use a digital multimeter for household wiring, testing batteries, power supplies, and electric motors.
They Are User-Friendly
Digital multimeters do not rely on a user’s ability to calculate the correct reading. Instead, they perform the calculations themselves and display the reading, which makes digital meters user-friendly. All you have to do, in order to get reading, is to place the needles of the multimeter in the place where the reading is to be taken, wait for the meter to display the reading, and write down the reading. This feature makes digital meters more usable and less time-consuming. Moreover, with the help of this feature, even complete beginners will not have any issues with using the meter.
