A reading of 10 may indicate 10 ohms, 10 kilo-ohms or 10 mega-ohms. If such occurs, switch directly to the next higher value selection.

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

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.

To check the voltage between two spots, follow the next steps: Touch the red cable pin end to one leg of the resistor and the black cable end to the other. 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. Sometimes, the knob is also used as an ON-OFF switch if one of the positions indicated at the dial turns the unit off.

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. 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.

A reading of “OL” or 0 while testing forward bias, and 0 while testing reverse bias indicates that the diode is bad. The black cable will remain at COM.

We make sure that dy9205a switch is at OFF position, which means the bulb gives no light at all. We may use conversion mulltimeter pixels from advertising networks such as Google AdWords, Bing Ads, and Facebook in order to identify when an advertisement has successfully resulted in the desired action, such as signing up for the HubPages Service or publishing an article on the HubPages Service.

ComScore is a media measurement and analytics company providing marketing data and analytics to enterprises, media and advertising agencies, and publishers. The screen will show you how much current flows to the bulb and of course, the bulb is at this point giving light. Finally, check the display on the dibital to see the voltage. Touch the two pin ends on the two spots between which the voltage is to be measured.

That said, be very cautious with your knob selection before trying to take any measurement. Plug the black cable on COM and the red cable on V socket of the multimeter. Then, set the multimeter to the kind of voltage you’re measuring if it doesn’t have an auto-range function. 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. Some also test diodes and continuity.

Call an electrician if you don’t know what you are doing.

Reverse the probes to test reverse bias. Precautions – Safety First! In most multimeters, the LCD screen is a unit dogital to display 3.

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 multiketer for easy access on circuit parts, and the other is a wider end, to be slotted on the multimeter’s sockets.

Continuity tests can only tell you if an internal connection is open or shorted. Voltage is the dt920a potential difference between two points and its unit is Volt V. A digital multimeter commonly has 3 or 4 sockets on some of which the test cables will be inserted. At the back of the unit, you can find the battery compartment, typically closed with a small screw. Some articles have Vimeo videos embedded in them. This is used for a registered author who enrolls in the HubPages Earnings program and requests to be paid via PayPal.

How can I know if a particular device is functional or faulty?

You can use a go across the two poles to see if there is continuity. A resistor is an electronic part, specifically made to increase the resistance at a spot of the circuit, thus controlling the current that goes through it, as needed for the device’s normal operation. Set the multimeter for the voltage you’re measuring.

multieter 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. If you are not knowledgeable at all about electricity, you should rather start learning some basic electronics theory: This is a dangerous situation which could burn your house down if there yse no earth leakage system in your house. Cookies make wikiHow better.

Every single thing in the world has a resistance, be it zero, small, high or infinite. Place the probes on either side of the break, observing polarity black probe on negative side, red probe on positive side. Put the black probe in the common terminal and the red probe in the terminal multieter for measuring volts and ohms. Set the multimeter to measure current.

In some measurements, you do not have to keep the device to be checked ON and running. Use the selector knob to choose the test diode function. Things You’ll Need Multimeter. 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 of much help to the professional.
