The oscilloscope is made with components that consist of an electron beam or gun, a medium-sized fluorescent screen, and varied encompassing controls or knobs that allow an operator to adjust … Best Oscilloscope for Hobbyist Read More »

Step 1: Reading and Changing the Oscilloscope Display. Every oscilloscope has a window that displays the voltage output of your signal. In every display, the y-axis is voltage, and the x-axis is time. You can zoom in and out of the display grid by adjusting the "Volts per division"* or "Seconds per division". A multimeter is a handy tool that you use to measure electricity, just like you would use a ruler to measure distance, a stopwatch to measure time, or a scale to measure weight. The neat thing about a multimeter is that unlike a ruler, watch, or scale, it can measure different things — kind of like a multi-tool. Conclusion: In this lab we used the oscilloscope to measure the current of several simple circuits. The oscilloscope let us actually see the current going through our setup and allowed us to manipulate it to acquire values and a different perceptive of this flowing energy. Connect the oscilloscope to any channel (they should all be the same since you tweaked them). Monitor the output voltage of the power supply, either with your volt meter or by the digital meters on the power supply. If the power supply doesn't have digital meters, use a digital multimeter. How to use an oscilloscope : Measuring Voltage and frequency Using the channel amplifier setting you can measure voltage here the amplifier is set to 0.2V per (vertical) division. Just adjust the channel amplifier setting until the signal you are looking at 'just' fills the screen - this gives the maximum (most accurate) view of the signal.

AC coupling can usually be selected from the channel settings of the oscilloscope. It blocks DC by inserting a capacitor in series with the input signal. AC While measuring the signal waveform by the oscilloscope through a probe, the output voltage of the circuit is measured by a tester. As you can see, the tester indicates AC 0.97V. Actually, the tester indicates the values of RMS (root-mean-square) voltage equivalent to the instantaneous AC voltage that is present at the moment.
