5 Top Reasons Why You Need to Switch to a Digital Multimeter
A digital multimeter is an electrical device that combines the functionality of a voltmeter, ammeter, ohmmeter and milliammeter. The device is used to measure electrical parameters such as voltage, current and resistance. The digital multimeter, unlike the analog multimeter, has an LCD screen for displaying the results, making it easy to use and provide accurate readings. Considering its portable size, ease of use and possession of digital and analog converters, it's a common tool for every electrician due to its effectiveness. Below are five top reasons why you need to switch to a digital multimeter.
1. Provide Accurate Readings
Unlike the analog multimeter where you are required to follow the needle indicator and focus on the scale for readings, the digital multimeter displays the readings on an LCD screen. The seven-segment display allows one to have more accurate readings, unlike other devices that round off the readings to only two decimal points. Also, the analog multimeter takes time to read and is highly prone to human error. One may easily interpret the wrong reading, causing a lot of adverse effects before the fault is realized.
2. Has Auto Polarity Functions
When taking voltage readings, a digital multimeter is capable of reading negative values. This usually happens when you place the probes in opposite poles, signifying a fault. In the case of an analog multimeter, placing the probes in opposite poles may cause the device to break, as it doesn't allow for negative readings.
3. More Versatile
Other than testing the voltage, ammeter and current, digital multimeters are more reliable and offer additional resistance. This means that you would only use one digital multimeter to test for voltage and resistance within a short time, as opposed to using an analog multimeter. In addition, digital multimeters have a high resolution, making them able to measure and note slight changes in the signal. Importantly, they are offered in smaller sizes, making them easy to carry around as opposed to analog multimeters.
Digital multimeters have no moving parts or exposed internal parts, making them highly durable. Analog multimeters may be easily damaged upon physical contact with the needle. The digital multimeter has a strong and durable LCD screen that won't be affected upon any physical contact.
With numerous technological advancements, digital multimeters have advanced integrated circuits that make the device less costly to manufacture and requires less power to operate. In addition, this has allowed smaller but powerful designs to be used in manufacture. Digital multimeters not only fit in your pocket easily but are also friendly to your pocket in terms of cost.
Therefore, are you in need of a multimeter or are considering to upgrade from your analog multimeter? If so, consider digital multimeters due to their increased functionality, ease of use and affordability.
