The Auto-Range Feature Auto range is a feature of some high-end multimeters in the market some of which, however, are not that expensive and can be multiketer much help to the professional.

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

More expensive and high-quality multimeters can have 4. DC voltage is the direct current voltage of batteries and is different from AC voltage, which is the alternating current voltage supplied for home appliances through our house wall sockets. Choose either the terminal marked for measuring 10 amps or the one marked for measuring milliamps mA.

For example, you can easily measure the resistance between two parts of your body; however, in a real lab, you would never make such measurement. However, an analog multimeter also got its advantages; to start with, it is preferred in some particular measuring tasks where a digital multimeter would show unreliable values. Place the red probe on the positive side of the diode and the black probe on the negative side.

Computers and Electronics In other languages: This allows for easy troubleshooting of damaged parts or for identifying the characteristics of an unknown part. In its various positions, each diyital of measurement is divided into many maximum values; for example, the resistance measurement area would include 5 different positions, one for Ohms, one for 2 Kilo-Ohms, one for 20 KOhms, one for KOhms and one for 2 MOhms.

Voltage is the electrical potential difference between two points and its unit is Volt V. This may be represented by the Dt9205x letter Omega, which stands for ohms, the unit of measurement for resistance. Help answer digita Learn more. The protection fuse is typically digjtal next to the battery, so it can be easily replaced if a mishap occurs such as wrong selection of rotating switch or any kind of short-circuit.


Javascript software libraries such as jQuery are loaded at endpoints on the googleapis. Suitable alligator clips for the pinpoint end of the test cables could be useful. Read the display, taking care to note the units. If you are not knowledgeable at all about electricity, you should rather start learning some basic electronics multimeted Auto range is a feature of some high-end multimeters in the market some of which, however, are not that expensive and can be of much help to the professional.

Instead, we will connect the red test cable at the one end of that wire and the black test cable in the other end. Disconnect the dryer switch from its circuit. Non-consent will result in ComScore only processing obfuscated personal data. This will be noted later too, at the stage where you will be trying to measure AC voltage or current. In the diagram, you can see voltage digjtal during normal operation.

Remember what we said about interrupting the circuit? Yes, I own one. 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.

Lately, the digital electronic multimeters are the vast majority of the multimeters sold, because as opposed to analog units which have a needle and a dial table, with a digital unit you can view the value to be measured on its LCD screen.

This article has also been viewedtimes. This supports the Maven widget and search functionality.

Thank you for your feedback! Put the black probe into the common terminal and the red probe into the terminal used to measure volts and ohms.

This may be represented by the letter A. Once you are sure that there is no power, remove the resistor you want to measure.

5 Ways to Use a Digital Multimeter – wikiHow

Check the reading of your multimeter. Comments are not for promoting your articles or other sites. The screen will show you how much current flows to the bulb and of course, the bulb is at this point giving light.

This may be represented by a symbol representing a diode, an arrow pointing at a vertical line.

Unless you are signed in to a HubPages account, all personally identifiable information is anonymized. C is to refer to the schematic diagram to where it is connected. In some measurements, you do not have to keep the device to be checked ON and running. If the display reads “OL overload ,” this indicates that reverse bias is good.


We know already that such bulb requires high diigtal and would probably be many Multimeteer, so we will choose the A socket of the multimeter, in which we will plug the red cable. Other possible sockets are temperature sockets, in which a 2-prong thermocouple with the ability to measure temperatures at its end can be plugged.

Electrical current is an indication of the number of electrons flowing at any given time, and its unit is the Ampere, symbolized as “A.

Not Helpful 3 Helpful 8. A negative value during a current measurement means that the flow of current is the opposite of what you expected when you connected the test cables. This is a cloud services platform that we used to host our service. Please choose which areas of our service you consent to our doing so. Every single thing in the world has a resistance, be it zero, small, high or infinite.

The rotating knob is technically a switch which indicates which measurement is to be taken. By continuing to use our site, you agree to our cookie policy. To measure fo, you must place the multimeter in series with the circuit.

This is a dangerous situation which could burn your house down if there is no earth leakage system in your house.

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 dt9205x checkthen the screen will show relative information about the part under check.
