Set the multimeter to measure current. Most DMMs include tiny little slots where the pins of the legs of a transistor or diode can be inserted – if the appropriate choice has been made through the rotating knob for example, pointing at transistor checkthen the screen will show relative information about the part under check.

Yes, I own one. Multimeters are small, lightweight and battery operated, and they can test a wide variety of electronic components in many situations, making them indispensable tools for anyone who needs to test and repair electronic circuits. No, I don’t think it is even needed.

It is a much-needed instrument for everyone who deals with projects which involve electricity because it can measure most characteristics of the circuit, such as voltage, current, resistance, while at the same time it can be used to troubleshoot damaged, burned, or failing electronic equipment and parts. Not Helpful 3 Helpful In some measurements, you do not have to keep the device to be checked ON and running. It comes in many different Ho values and has specific coloring stripes on its surface, so its resistance is known.

The Multimeter A multimeter is a portable electronic instrument with relatively small size and weight, which combines multi-range voltage, current and resistance meter. Thus it can be of much use in initial studies of electronics. If you’re measuring DC voltage or millivoltage, you’ll need to place the black probe on the negative side of the component and the red probe on the positive side.


How can I know if a particular device is functional or faulty? The easiest measurement a kultimeter can make is a resistance measurement. If there’s a reading, the fuse is dead. Turn the power on.

Unless you are signed in to a HubPages jse, all personally identifiable information is anonymized. Computers and Electronics In other languages: The terminal may also be marked for testing diodes.

DT9205A Digital Multimeter. Measure DC /AC current, voltage, resistance, capacitance, hFE, diode

If you’re unsure of the current, start in the 10 amp terminal until you’re sure the current is less than milliamps. In most multimeters, the LCD screen is a unit able to display 3.

Observe polarity when measuring DC voltage or millivoltage. This may be represented by the letter A. When it is on, it should show a zero reading with a beeping sound from your meter and, when off, there should be a reading and no beeping sound. Put one lead red of your multimeter to one contact of your switch and the black lead of your multi meter to the other contact of your switch.

This is an ad network. The current will run through the circuit, up the red probe and through the multimeter, then out the black probe and into the circuit.

5 Ways to Use a Digital Multimeter – wikiHow

The multimeter will beep each time a new voltage is detected. This is used to detect comment spam. This happens because current can only be measured in serialnot in parallel as voltage is measured.

ComScore is a media measurement and analytics company providing marketing data and analytics to enterprises, media and advertising agencies, and publishers. Please don’t hesitate to contact me with comments, questions or arguments, and thank you for taking the time to read a quite large article.

The test cables are also provided with the multimeter what it is bought and are a red and a black cable, one side ends at a pinpoint for easy access on circuit parts, and the other is a wider end, to be slotted on the multimeter’s sockets. Not Helpful 3 Helpful 8. If you see “1” or over-range, then you need to switch to the next higher value – if you see a too low value, you need to switch down to lower selections, so you get more reliable value display.

Let’s take for example a simple, 2 pin resistor: Some articles have Google Maps embedded in them. If you are not knowledgeable at all about electricity, you should rather start learning some basic electronics theory: Not Helpful 1 Helpful 2. The reason that a different socket for large current exists is that inside the multimeter a larger shunt resistor is used. If the display reads “OL overload ,” this indicates that reverse bias is good.

Twist the selector knob to set the multimeter to measure resistance.

Precautions – Safety First! This is a cloud CDN service that we use to efficiently deliver files required for our service to operate such as javascript, cascading style sheets, images, and videos. A multimeter with such feature can identify the magnitude of the measurement and will range directly to the appropriate level of value, something which eliminates the need of many different knob multieter for the same kind of measurement. Other possible sockets are temperature sockets, in which a 2-prong thermocouple with the ability to measure temperatures at its end can be plugged.

Thank you for your feedback! This is a cloud services platform that we used to host our service. Some multimeters will beep when the reading is less than 1.

Set your multimeter to continuity test. Some articles have YouTube videos embedded in them. Not Helpful 0 Helpful Yes, I tried it once multimeher another person’s instrument. Supposing that you have the knob at the V position, the value you will see at the multimeter screen would not have many decimals so that you could switch to 20 V instead. Not Helpful 2 Helpful 5.
