Today, digital multimeters are used to measure values such as voltage, current and resistance. As such, digital sphygmomanometers have become a popular choice. Is it just because it’s digital? Does he make better choices than his peers? Here are some possible reasons.
What does a digital multimeter do?
As mentioned above, a multimeter is a basic device that can perform many functions of units of measurement such as voltage, current and resistance. Also known as multistage, larger models are used to improve other electronic devices because they are more sensitive and accurate. However, it is available in digital multimeters and analog multimeters. But the former is more popular than the latter.
Advantages of digital multimeters
The great thing about digital multimeters is that they offer more accurate analog measurements. Accuracy is not limited to providing accurate results. However, the analog shows the value of the scale by injecting the scales. But a digital multimeter has an LED display or LCD display that can display input to the decimal point as a digital feed. This makes it very special and readable. It can also be adjusted to measure ohms, amps and voltages as needed.
Advantages of analog meters
An analog multimeter is also ideal for measuring voltage, current, resistance, frequency and signal strength. However, some users have criticized him for being too old. But it also has advantages over digital multimeters. For example, examining diodes with an analog multimeter is more accurate than using a digital multimeter. The latest analog multimeters, in addition to the digital version, have the best features such as capacitors, diodes and iC test modes.
Choosing a digital or analog multimeter depends on your needs. You can choose them all!
Return to the sample test. When the power supply is not connected, you must create a multimeter to measure resistance. All you have to do is set the rotation a few meters to ohm. (Ohm is a measure of resistance.) If you combine two test probes. (Red is positive, black is negative) The ohmmeter shows zero resistance. Undoubtedly, there is absolute continuity – which is certainly logically justified.
By reading zero you have a closed circuit that runs a current.
This knowledge is very useful if you want to check the lamp below. If you take the lamp out of the lamp and push the probe down the lamp, take another probe and press the lamp socket towards the subject. You can best multimeter do a continuity check on the lamp. A zero resistance reading means that the circuit is off. So the lamp works well. If the meter shows a continuum, the lamp is bad – the fuse is gone and the current can not pass through it.
In fact, you can do the same test on both ends of the power cord. If the multimeter does not show continuity, it indicates that the circuit is open, which indicates a problem with the cable – it may be interrupted. Remember though that you should not check the continuity of any cables or devices. Turn on the power and always plug in the power cord before each test. About electronic tests
If you want to test the switch with a digital multimeter when using a multimeter (also called a multimeter), press the probe on each side of the switch. (Each side is called a switch tip). When you switch the switch from off to on.
Your multimeter shows the change from zero to read.
(Key to show relevant) Unlimited. Your switch is working properly because it works perfectly. And do not expect the switch to work continuously as no current can be passed through. If your switch does not work properly, you can test the motor in the same way by connecting a test probe to each shaft. The same key applies to testing. The zero reading shows the continuity when current flows and the motor produces a sound.
These are just a few basic tests.
But if you follow the instructions of the digital multimeter. You can do more accurate tests. If you want to use a multimeter to test the battery, several tests can be done because the meter can detect alternating current (AC) and direct current (DC). You need a DC board multimeter to check that the battery is fully charged.
