Accessing signals Probe Compensation : Probe Compensation Adjust the probe on 1x or 10x according to the signals.
If you see a “Undercompensation” or “Overcompensation” waveform display, adjust the variable capacitor on the probe with a screwdriver with non-metal handle, until a “Correct Compensation” waveform Automatic settings for waveform display : Automatic settings for waveform display Connect the signal to be measured to the signal input channel.
Press [AUTO]. The oscilloscope will automatically set the vertical deflection factor, scanning time base and trigger mode. Vertical System : Vertical System Turn the vertical position knob to display the signal in the centre of the window.
Change the vertical setups and check changes of status information. Horizontal System : Horizontal System Use the horizontal scale knob to change the horizontal time base setup and check any changes in status information.
Range of horizontal scanning rate is 5ns~50s, in steps of 1-2-5.

Your oscilloscope can automatically measure most display signals. To measure signal frequency and
peak-to-peak value, follow the steps below:
1 .Press [MEASURE] to display the auto measurement menu.
2 .Press [F1] to enter the measurement type option menu.
3 .Press [F3] to select voltage.
4 .Press [F5] to go to page 2/4, then press [F3] to select measurement type: peak-to-peak value.
5 .Press [F2] to enter the measurement type option menu, then press [F4] to select time.
6 .Press [F2] to select measurement type: frequency. Questions? : Questions? Thank You! : Thank You!
