If you are measuring a resistor of 1. If you’re measuring AC voltage, place the probes across the component. C to consider also. Place the probes on either side of the break, ddigital polarity black probe on negative side, red probe on positive side. This is used to prevent bots and spam.
DT9205A Digital Multimeter. Measure DC /AC current, voltage, resistance, capacitance, hFE, diode
Resistance is relevant to continuity, which is also a measurement most multimeters can make. Sign in or sign up and post using a HubPages Network account.
It comes in many different Ohm values and has specific coloring stripes on its surface, so its resistance is known. Connect the multimeter to the circuit. When taking a particular measurement watch out with regards to what you are touching and keep yourself insulated against the parts with electricity flow.
Read the display, taking care to note the units.
Switch the rotating knob to the resistance area and choose the 2 KOhm position. You can now compare your readings to the schematics.
DTA Digital Multimeter. Measure DC /AC current, voltage, resistance, capacitance, hFE, diode
ues It is a much-needed instrument for everyone who deals with projects which involve electricity because it multlmeter 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.
In such multimeters, there would be only one knob selection for each measurement, that means one for resistance, one for DC, etc. Not Helpful 2 Helpful 5.
In most multimeters, the LCD screen is a unit able to display 3. 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. As a result, measuring any kind of electrical characteristic is easier, because it requires no specific selection of possible value beforehand.
If you’re unsure of the current, start in the 10 amp terminal until you’re sure the current is less than milliamps. If there’s a reading, the fuse is dead. Most units available in the market go a step beyond those measurements, by adding transistor and diode tester, continuity tester, thermometer and capacitance meter, though units with the latter abilities cost more and tend to be less reliable than a specialized instrument for the same purpose.
A reading of less than ohms indicates good continuity.

The rotating knob is technically a switch which indicates which measurement is to be taken. An electronic multimeter is the very first instrument an electronics engineer will have to buy, even before buying soldering tools such as iron, solder, and boards. Unless you are signed dt92005a to a HubPages account, all personally identifiable information is anonymized.
The black cable will remain at COM. Choose either the terminal marked for measuring 10 amps or the one marked for measuring milliamps mA. The polarity doesn’t really matter – you would never see a negative resistance value because such thing does not exist.
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. Also, test continuity between live and earth to see if there is a possible short circuit. That said, be very cautious with your knob selection before trying to take any measurement.
There are “passive” devices around the I.
