For example, you can easily measure the resistance between two parts of your body; however, in a real mjltimeter, you would never make such measurement. The reason that a different socket for large current exists is that inside the multimeter a larger shunt resistor is used.

Remember what we said about interrupting the circuit? Connect the multimeter to the circuit. C to consider also. A reading of “OL” or 0 while testing forward bias, and 0 while testing reverse bias indicates that the diode is bad. Suitable alligator clips for the pinpoint end of the test cables could be useful.

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

Some articles have Vimeo videos embedded in them. This is an ad network. This will be noted later too, at the stage where you will be trying to measure AC voltage or current. When taking a particular measurement watch out with regards to multimmeter you are touching and keep yourself insulated digotal the parts with electricity flow.

To check the voltage between two spots, follow the next steps:. 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.

The easiest measurement a multimeter can make is a resistance measurement. For example, in most occasions, resistance can be measured without the unit to be powered.

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. The current will run through the circuit, up the red probe and through the multimeter, then out the black probe and into the circuit.

Secondly, a unit with a needle is a good place to start for those who are amateurs but would like to venture deeper into the electronic field; after all, an analog multimeter gives a better sense of the values and units of each characteristic to be measured.

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. A digital multimeter operates using a 9 V brick-style battery. Help answer questions Learn more. ti

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

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.

Supposing that you have the knob at the V position, the value you will see at the multimeter screen would not have many decimals so that you could switch to 20 V instead. You can use this to streamline signing up for, or signing in to your Hpw account. In such multimeters, there would be only one knob selection for each measurement, that means one for resistance, one for DC, etc.

5 Ways to Use a Digital Multimeter – wikiHow

Observe polarity when measuring DC voltage or millivoltage. Once you are sure that there is no power, remove the resistor you want to measure. This is a cloud CDN service that we use to efficiently deliver files required for our service to operate such as javascript, cascading style sheets, images, and videos.

This supports the Maven widget and search functionality. Connect the multimeter to a circuit. By continuing to use our site, you agree to our cookie policy. This is used to prevent bots and spam. That’s why it’s always better to measure a value at its next higher value selector. Check the reading of your multimeter.

This is because there is no need to have any power on the circuit to proceed howw a resistance check though there are devices whose resistance differs when under power supply.

If the display reads “OL overload ,” this indicates that reverse bias is good.


Some multimeters will beep when the reading is less than 1. Javascript software libraries such as jQuery are loaded at dt92205a on the googleapis. Touch the red cable pin end to one leg of the resistor and the black cable end to the other.

The multimeter will display the voltage of the battery under check. Read the display, remembering whether you are measuring amps or milliamps. Every single thing in the world has a resistance, be it zero, small, high or infinite. multimetre

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.

No data is shared unless you engage with this feature. Sign in or sign up and post using a HubPages Network account. Not Helpful 2 Helpful 5. Measure AC voltage by placing the probes across the component. Read the display, taking eigital to note the units. No data is shared with Facebook unless you engage with this feature.

I would personally avoid plugging the test cables in a wall socket of my house if I was not aware of the dangers and if I had not double and triple-checked the multimeter settings. Lately, the digital electronic multimeters are the vast majority of the multimeters sold, because as opposed to analog units which have a needle and a dial table, with a digital unit you can view the value to be measured on its LCD screen.

Precautions – Safety First! 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. If you keep seeing a negative value, for example -5 V, you have either connected the black and red test cables pin ends the wrong way, or you have connected them correctly; that means you are really measuring a negative voltage, something not rare at all because there are circuits which need symmetric power supply, able to provide positive and negative voltage.
