4.2.1P-P Voltage Measurements
Step :
(1) Input signal to INPUT [19] terminal.
(2) Setup VOLTS/DIV and observe waveform, set waveform display on the screen within 5
divisions, and turn VAR clockwise to the calibration position.
(3) Adjust level to make waveform steady.
(4) Adjust sweep controls to show at least one cycle of the waveform is on the screen.
(5) Adjust vertical position to ensure the bottom of waveform lies on a horizontal axis on the
screen. Fig 4-3A.
(6) Adjust horizontal position to ensure the top of waveform lies center of vertical axis. Fig 4-3B.
(7) Read the divisions between A-B on vertical direction.
(8) Calculate the signal Vp-p using the formula below :
Vp-p= DIV of vertical direction

Sensitivity
For example, In Fig 4-3, vertical divisions of A-B is 4.1 DIV, sensitivity of the 10:1 probe is
2V/DIV, then Vp-p=2
