How To Measure Volts, Amps And Ohms With A Digital Multimeter - Digital Voltmeter _______________________________________ By John - http://digitalvoltmeter.org/
A digital multimeter is a versatile tool that integrates three testing devices - a voltmeter, ammeter, and ohmmeter - into one easy-to-use handheld unit. Here is a simple and straightforward guide on how to use each of the testing functions contained in a multimeter. To Learn More About Click Here Voltage, which is essentially the electrical potential of a device, is measured with a voltmeter.
To use the voltmeter function to measure DC volts, turn the function switch to "V=" setting. Connect the black and red leads to the multimeter. The red lead you will connect to the red input terminal which is labeled "V立." The black lead you need to connect to the terminal that is labeled "COM," which stands for "common terminal." Once the leads are connected, you are ready to measure the voltage of a circuit. Attach the red lead to the terminal with the higher potential; attach the black lead to the terminal with the lower potential.
Amps are the amount of electrical current that flows in an electric circuit.
For measuring amps with the ammeter function, you will need to connect the leads differently than you did with the voltmeter. The first step is to set the function switch to the "A=" point on the dial. Next, connect the red lead to the terminal that says "300mA," and connect the black lead to the terminal labeled "COM." When you have attached the leads as described, you can now connect the meter in series to the device you wish to measure. Just open up the circuit and insert the meter between the open points and you can measure the amps. You will see the results as milliamps, as you are using the 300mA terminal.
