This Digital multimeter is a kind of convenient operation, accurate reading, complete function, small size, easy to carry and use battery as power, handheld and. Learn how you can make all kinds of electronic measurements using a cheap, portable instrument called digital multimeter. The DTA Digital Multimeter is a precision, battery powered, /2 digit To avoid electrical shock, use caution when working above 60VDC or 25VAC rms.

A multimeter, also called a volt-ohm meter or VOM, is a device that measures resistance, voltage and current in electronic circuits. This is a cloud services platform that we used to host our service.
5 Ways to Use a Digital Multimeter – wikiHow

The current will run through the circuit, up the red probe and through the multimeter, then out the black probe and into the circuit. Keep the cables connected as before, switch the rotating knob to ACV or AC Voltage, choose the appropriate value position and touch the one end on the phase and the other on the neutral or ground slot in your wall socket.

uwe As a result, measuring any kind of electrical characteristic is easier, because it requires no specific selection of possible value beforehand. If you’re measuring AC voltage, place the probes across the component. Not Helpful now Helpful A reading of “OL” or 0 while testing forward bias, and 0 while testing reverse bias indicates that the diode is bad.
It’s not necessary to observe polarity. This happens because current can only be measured in serialnot in parallel as voltage is measured.
It depends on the type of switch.
DT9205A Digital Multimeter. Measure DC /AC current, voltage, resistance, capacitance, hFE, diode
The black cable will remain at COM. Check the reading of your multimeter. Insert the black probe into the common terminal and the red probe into the terminal marked for measuring ohms, volts or diode test.
That’s why it’s always better to measure a value at its next higher value selector. This makes the process much easier for the hobbyist but the professional engineer as well.
Measure AC voltage by placing the probes across the component. 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 multimetr equipment and parts.
All these conditions represent a digiital shock hazard. Integrated circuits cannot be tested with continuity unless you are miltimeter with the pin assignments, i. Turn the power on. Multimeters are small, lightweight and battery operated, mhltimeter 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.
Warnings Never use a multimeter to test whether a high-voltage circuit is dead, on circuits that use more than watts, on a main power supply to a building, when the multimeter’s battery is low or if its probes are damaged. Put the black probe into the common terminal and the red probe into the terminal used to measure volts and ohms. Remember what we said about interrupting the circuit? 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 kse we will plug the red cable.

We dlgital sure that the switch is at OFF position, which means the bulb gives no light at all. 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 multimeterr.
Physical Appearance and Ports A digital voltmeter consists of the following: If it’s zero, the fuse is fine. To check the voltage between two spots, follow the next steps: If such occurs, switch directly multimeteg the next higher value selection. A digital multimeter commonly has 3 or 4 sockets on some of which the test cables will be inserted.
In general, if multimeteg knob’s indicator shows towards DCV 20 V, then the user will measure the direct current voltage of a circuit which is less than 20 V. This is a dangerous situation which could burn your house down if there is no earth leakage system in your house.

Set the multimeter to measure current. C is to refer to the schematic diagram to where it is connected.
