In this video I am showing How to use digital multimeter and how to read DC and AC voltagescurrentresistencecontinuitycapatiance and temperatures all the. Put the red probe in the mA jack and the black probe in.
First plug the meters black probe into the jack marked -.
Digital multimeter how to use. Digital multimeter 1Turn on the instrument. The first step is to press the power button to turn on the instrument. Digital multimeters operate on battery or AC power so if the instrument doesnt turn on youll want to either replace the battery or check the power supply.
2Select a mode and range. How To Check Voltage With A Multimeter. A digital multimeter allows you to measure both AC alternating current and DC direct current voltage.
Commonly AC voltage measurement can be applied to sockets TVs and other electrical systems in your house while DC can be applied to batteries. In this video I am showing How to use digital multimeter and how to read DC and AC voltagescurrentresistencecontinuitycapatiance and temperatures all the. A digital multimeter is used to check the ohm or kohm of any register.
200 2000 20k 200k 2000k mark of meter is used to measure resistor ohms. The negative lead should be placed on COM and the positive lead on VmA. Check Continuity And Diode The most useful digital meter is the community check.
Set your multimeter to the continuity setting using the selection knob. The readout on the screen will instantly read 1 which means that there isnt any continuity. This would be correct since we havent connected the probes to anything yet.
Next make sure the circuit is unplugged and has no power. A multimeter gives you useful insights into how your circuits are working. You can use a multimeter to check if the switch is on or if the conducting wire in a circuit is broken.
It also comes in handy when determining the amount of current flowing in a circuit. It can help you know the power left on your batteries. Understanding AC and DC.
When using a digital multimeter to measure current the multimeter should be connected in series with the circuit being measured. To minimize instrument loss resistance caused by connecting the digital multimeter the multimeters current measurement circuit is designed to have low impedance. It can be used to test a switch or a fuse.
Before you test make sure that there is no current going trough the object youre testing. Then put your black probe in your multimeters COM port and the red probe into the port marked VΩmA. Next select the continuity setting with the dial on your multimeter.
How to Measure AC Voltage with Digital Multimeter. For reading the single phase AC voltage 180Vac-230Vac set the selection knob of the digital Multimeter on the AC voltage. While the Digital Multimeter test leads are connected use these test leads to measure the AC voltage.
Starting with the simplest most basic test use the voltage mode on your meter to check battery output. First plug the meters black probe into the jack marked -. Use a Digital Multimeter.
Some products of technology can be overwhelming to get at first but once its working and usage is understood it becomes a great asset in the hands of the user. A digital multimeter is a similar electronic device seemingly complex but of great usage. It is a handheld device used to measure 2 or more electrical values-primarily voltage current and resistance.
A multimeter or a multitester also also called a VOM volt-ohm-milliammeter is an electronic measuring instrument that performs several measurement functions in one unit. A typical multimeter can be used to measure voltage current and resistance and even to check for conductivity. How to use a digital multimeter The operation of a DMM itself is normally very straightforward.
With a knowledge of how to make voltage current and resistance measurements it is then a matter of putting the multimeter to use. If the meter is new then it will obviously be necessary to. Heres how to use the multimeter to measure DC current.
Turn on the power button of your EverStart Multimeter. A DC current score A and a straight line are utilized as an icon to present the DC current measuring mode. You can turn the dial in it.
Put the red probe in the mA jack and the black probe in. A DMM digital multimeter is an electronic measuring device for current. It clearly shows the measured values as numerical values on the display.
You can use it to carry out a variety of current tests. Even inexpensive measuring instruments for hobby use measure the standard values of electrical voltage electrical current and ohmic resistance. Using Digital Multimeter we can check all the parameters and components.
The voltage is measured with a voltmeter. Current is measured with an Ampere meter. The resistance of the resistor is measured by ohm Ω meter.
There are separate meters to. The multimeter has two probes red and blackpositive and negative. They are used to connect with the circuit.
And a display shows its measuring values. If you are a beginner and just starting how to use digital multimeter then this article will helpful for you. In this tutorial you will learn -.
