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.

Plug the black cable on COM and the red cable on V socket of the multimeter. This is used to identify particular browsers or devices when the access the service, and is used for security reasons. Place the red probe on the positive side of the diode and the black probe on the negative side. If you’re unsure of the current, start in the 10 amp terminal until you’re sure the current is less than milliamps.
In the continuity test, usually shown with the symbol of a diode, most multimeters will produce a “beep” sound when the 2 parts of the circuit on which the two end tips of the unit have been connected are electrically connected means the resistance between them is near zero.
Turn the power on. 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. Did this summary help you? To provide a better website experience, turbofuture. One effective way of testing the condition of an I.
Finally, check the display on the multimeter to see the voltage. The reason that a different yse for large current exists is that inside the multimeter a larger shunt resistor is used. Not Helpful 0 Helpful When taking a particular measurement watch out with regards to what you are touching and keep yourself insulated against the parts with electricity flow. Observe polarity when measuring DC voltage or millivoltage.
The rotating knob is technically a switch which indicates which measurement is to ,ultimeter taken. Yes, I own one.
Most often what you will be checking is the resistance between two parts of a circuit or the resistance value of a resistor. A multimeter with such feature can identify the magnitude of the measurement and will range directly to the appropriate level of value, something which eliminates the need of many different knob positions for the same kind of measurement.
This is because there multi,eter no need to have any power on the circuit to proceed with a resistance check though there are devices whose resistance differs when under power supply. This allows for howw troubleshooting of damaged parts or for identifying the characteristics of an unknown part. If the display reads “OL overload ,” this indicates that reverse bias is good.
A reading of 10 may indicate 10 ohms, 10 kilo-ohms or 10 mega-ohms. To start with, you are dealing with electricity which could probably be dangerous, if not lethal. 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. This service allows you to sign up for or associate a Google AdSense account with HubPages, so that you can earn money from ads on your articles.
C to consider also. It comes in many different Ohm values and has specific coloring stripes on its surface, so its resistance is known.
Also, test continuity between live and earth to see if there is a possible short circuit. Read the display, remembering whether you are measuring amps or milliamps. Check the reading of your multimeter. Put the black probe in the common terminal and the red probe in the terminal marked for measuring volts and ohms. To measure current, you must place the multimeter in series with the circuit.
To create this article, 18 people, some anonymous, worked to edit and improve it over time. In its various positions, each kind 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.
If your multimeter has an auto-range function, it’s not necessary to select the voltage you’re measuring. A multimeter is a portable electronic instrument with relatively small size and weight, which combines multi-range voltage, current and resistance meter.
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. As a result, measuring any kind of electrical characteristic is easier, because it requires no specific selection of possible value beforehand. The Multimete A multimeter is a portable electronic instrument with relatively small size and weight, which combines multi-range voltage, current and resistance meter.
DTA Digital Multimeter. Measure DC /AC current, voltage, resistance, capacitance, hFE, diode
ComScore is a media measurement and analytics company providing marketing data and analytics to enterprises, media and advertising agencies, and publishers. That’s why it’s always better to measure a value at its next higher value selector. 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.
Not Helpful 3 Helpful 8. Secondly, a unit with a needle is a good place to start for those who are amateurs but would like to venture digitsl into the electronic field; after all, dt9205s analog multimeter gives a better sense of the values and units of each characteristic to be measured.
Insert the black probe into the common terminal and the red probe into the terminal marked for measuring ohms, volts or diode test. Voltage is the electrical potential difference between two points and its unit is Volt V.
Precautions – Safety First! This is used to display charts and graphs multineter articles and the mulrimeter center.

However, an analog multimeter also got its advantages; to start with, it is preferred in some particular multimeted tasks where a digital multimeter would show unreliable values. This happens because current can only be measured in serialnot in parallel as voltage is measured. Place the leads on either side of the section of circuit you’re testing.
Set your multimeter to continuity test. The easiest measurement a multimeter can make is a resistance measurement.
