Measure AC voltage by placing the probes across the component. Not Helpful 1 Helpful 2.

Observe polarity when measuring DC voltage or millivoltage. This makes the process much easier for the hobbyist but the professional engineer as well.

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

The polarity doesn’t really matter – you would never see a negative resistance value because such thing does not exist. It depends on the type of switch. A negative value df9205a a current measurement uae that the flow of current is the opposite of what you expected when you connected the test cables.

Plug the black cable on COM and the red cable on V socket of the multimeter. Resistance is relevant to continuity, which is also a measurement most multimeters can make.


Include your email address to get a message when this question is answered. Can you tell us which parts were out of date so we can update them?

To use a digital multimeter to measure voltage, start by putting the black probe in the common terminal and the tl probe in the terminal that’s dt9205q for measuring volts. Toggle your switch and check the readings on the multimeter. Thank you for your feedback! This us used to identify particular browsers or devices when the access jultimeter service, and is used for security reasons. In most multimeters, the LCD screen is a unit able to display 3. Place the red probe on the positive side of the diode and the black probe on the negative side.

A reading of “OL” or 0 while testing forward bias, and 0 while testing reverse bias indicates that the diode is bad. If you are measuring a voltage of 22 V at the 20 V selection, the meter would either show “1” or some kind of indication for over-range. Some articles have Google Maps embedded in them. We partner with Say Media to deliver ad campaigns on our sites.

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. Set your multimeter to continuity test or where it shows the diode sign. For example, an electrically insulated material, such as a piece of wood, will show almost infinite resistance to current, which digtial current can’t go through it.


If it’s zero, the fuse is fine. Google provides ad serving technology and runs an ad network. There are “passive” devices around the I. Various switches might exist diyital a multimeter unit, depending on its quality and essentially its price; it can be switched to adjust the LCD brightness, to enable or disable audio, to activate auto-range, to hold a displayed value, etc.

How can I know if a particular device is functional or faulty? We know already that such bulb requires high wattage and would probably be many Amperes, so we will choose the A socket of the multimeter, in which we will plug the red cable.

As a result, measuring any kind of electrical characteristic is easier, because it requires no specific selection of possible value beforehand. Set your multimeter to continuity test. Also, test continuity between live and earth to see if there is a possible short circuit. 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.

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.
