How to use Digital Multimeter
Multimeter is powerful Electronics Instrument used to measure voltage diff.,current,resistance,connection short. So,if you are new in “Electronics” field you must know how to operate Multimeter. This article will provide you all information you need about Multimeter. Voltage measurement Current measurement Resistant measurement Short connections hFE value of Transistor Incoming search terms:maltimiter (1)
How to measure Current using Multimeter
Current is measure of flow of electrons in a wire, unlike voltage measurement in this you have to connect the Multimeter in series to those connections in which you would like to know Current value. Rotate your Multimeter’s pointer and make it point toward A sign. Now connect two Multimeter wires to two connections in which you want to see current, you can choose any value between 0 – 1000A….
How to measure AC Voltage using Multimeter
Voltage is potential drop between two points, a simple “Multimeter” can measure up to 750V AC, but it is really not safe to use Multimeter at 750V. But under safety limits we can use Multimeter up to 230V AC. Rotate your Multimeter’s pointer and make it point toward V~ sign, connect two Multimeter wires to two connections in which you want to see voltage ,you can choose any value like…
How To Find Short Connections Using Multimeter
Sometimes when you are making a project you may need to see whether any of your connections are short or not. If you have a wire and you want to know if it is braked or not then you need to follow these instructions Rotate your Multimeter’s pointer and make it point toward beep sign, connect two Multimeter wires to two connections in which you want to see short connections…
How To Measure DC Voltage Using Multimeter
Voltage is potential drop between two points, a simple “Multimeter” can measure up to 1000V, but it is really not safe to use Multimeter above 100V. Under safety limits we can use Multimeter up to 36V. Rotate your Multimeter’s pointer and make it point toward V sign, connect two Multimeter wires to two connections in which you want to see voltage ,you can choose any value between 0 – 1000V…
How To Measure Resistance Using Multimeter
Resistance is measure of blocking of Current and measured in ohm. Resistances comes with color coding ,you can measure resistance using color code method following are the values assigned to different colors. Black 0 Brown 1 Red 2 Orange 3 Yellow 4 Green 5 Blue 6 Violet 7 Grey 8 White 9 Gold 5% Silver 10% No…
How To Check LED Using Multimeter
LED is basic electronic component used to see outputs,you may required to see whether your LED is in the working condition or which leg is positive and which is negative. The leg which is longer in length is positive and other is negative, even if the legs of led are of same length you can know by seeing which leg is positive , as shown in figure . Since…
How To Check hFE Value Of Transistor Using Multimeter
hFE value( beta value) of transistor is used to find Amplification factor. Transistor has 3 legs named Base,Emitter and Collector which you can see from transistor’s data sheet from which you can also know the type of transistor whether it is npn or pnp. Rotate your Multimeter’s pointer and make it point toward hFE sign. Put the transistor in the left space according to its type and you will get…
