Applications of CRO
The CRO is a versatile laboratory instrument. It is used for all types of measurements like AC/DC voltage, AC/DC current, frequency and phase measurements. These methods are given below.
Measurement of AC/DC voltage
Measurement of AC voltage: With this method, we can measure the peak value of AC voltage. Connect unknown AC voltage across y-input of CRO. A following type of waveform will be displayed on the screen.
Measure its peak displacement in centimeters on graticule scale. Note down the position of Volt/div scale in Volts. Then using the formula calculate the peak value Vp –
