User’s Key points : 

User’s Key points We must want to know some important key points before using the equipment under consideration. General check Functional check Probe compensation Automatic settings for waveform display Getting to know the vertical system Getting to know the horizontal system Getting to know the trigger system

General Check : 

General Check Check the unit for possible shipping damages Check the accessories Thorough inspection of the entire unit

Functional Check : 

Functional Check Power on the unit and default setup 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. Use the horizontal position knob to adjust the horizontal position of the waveform window Press [MENU] to display the ZOOM menu. Shortcut Key Return to Zero!

Trigger System : 

Trigger System Use the trigger level knob to change the trigger level. Open the [TRIGGER MENU] to change trigger setups. Press [F1] and select EDGE TRIGGER Press [F2] and set TRIGGER SOURCE to CH1 Press [F3] and set EDGE TYPE as RISING Press [F4] and set TRIGGER MODE as AUTO Press [F5] and set TRIGGER COUPLING as DC Press [50%] and set the trigger level at the vertical centre point of the trigger signal amplitude.

Practical Example Scenario : 

Practical Example Scenario Automatic measurement of signal voltage and time parameters 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.
