Turn the POWER on. Apply a signal to the input terminal. Set the INTENSITY and FOCUS controls correctly, the spot will be reasonably bright, and as sharply focused as possible .
The TIME/DIV control determines the horizontal scale of the graph which appears on the oscilloscope screen.The VOLTS/DIV control determines the vertical scale of the graph drawn on the oscilloscope screen. The Y-POS allows you to move the spot up and down the screen.
When a sinusoidal signal is applied, you will obtain a clear and stable sine waveform trace on the screen.
Amplitude, peak-peak voltage , time period can be measured from the graph.
