OWON PDS5022S (01) PDF Document

To verify the normal operation of your OWON PDS5022S, follow these steps:

1. Connect the instrument to power and push the power switch button.

2. After the system completes self-checks, press the UTILITY button to access the FUNCTION menu.

3. Push the F2 button to select Recall Factory.

4. Set the switch on your oscilloscope probe to 10X and connect it to the CH1 channel.

5. Align the probe slot with the CH1 connector, tighten it, and connect the probe tip and ground clamp to the probe compensator connector.

6. Press the AUTO SET button. A 1KHz square wave with 5V peak-to-peak value will display in a few seconds.

When you connect a probe to an input channel for the first time on the OWON PDS5022S, you must perform this adjustment:

1. Set the probe attenuation coefficient in the menu to 10X and set the probe switch to 10X.

2. Connect the probe to the CH1 channel and attach the probe tip to the probe compensator signal connector. Connect the reference wire clamp to the ground wire connector of the probe connector.

3. Press the AUTOSET button.

4. Observe the displayed waveform and adjust the probe until a correct, flat-top square wave is achieved.

To ensure accurate vertical scale readings on the OWON PDS5022S, follow these steps:

1. Press the menu button for the channel you are using.

2. Push the selection button corresponding to Probe until the correct set value (1X, 10X, 100X, or 1000X) is shown.

3. Ensure the physical attenuation switch on the probe matches the setting selected in the menu.

Note: When the attenuation switch is set to 1X, the bandwidth of the OWON PDS5022S is limited to 5MHz.

Self-calibration helps the OWON PDS5022S reach optimum conditions. This is recommended if the ambient temperature varies by 5 degrees Celsius or more. Perform these steps:

1. Disconnect all probes or wires from the input connectors.

2. Press the UTILITY button to call out the FUNCTION menu.

3. Push the F3 menu selection button to select Perform Self-Calibration.

4. Press F3 again when the confirmation window pops up to run the program.

Do not contact any input channels until the calibration is finished.

The OWON PDS5022S supports mathematical operations between channels. To perform them:

1. Press the MATH MENU button to call out the WAVE MATH menu.

2. Press the F3 menu selection button to choose the desired operation (CH1-CH2, CH2-CH1, or CH1+CH2).

The calculation result will be displayed in the screen. You can refer to the following capabilities:

To use FFT on the OWON PDS5022S, ensure the horizontal menu is set to main timebase, not window setting mode. Then follow these steps:

1. Press the MATH MENU button, then press F1 to turn on FFT.

2. Press F2 to select the source (CH1 or CH2).

3. Press F3 to choose the window (Rectangle, Hamming, Hanning, or Blackman).

4. Press F4 to switch the format between dB and Vrms.

5. Press F5 to select the zoom multiple (1, 2, 5, or 10).

6. Use the Horizontal knob to move the waveform.

To capture non-periodic signals like pulses or burrs on the OWON PDS5022S, follow these instructions:

1. Set the probe attenuation to 10X in both the menu and the probe switch.

2. Adjust the VOLTS/DIV and SEC/DIV knobs to define a proper range.

3. Press the ACQUIRE button and select Peak Detect.

4. Press the TRIG MENU button, select Edge for type, Rising for slope, and Single for the mode.

5. Rotate the LEVEL knob to set the trigger level.

6. Push the RUN/STOP button. The OWON PDS5022S will wait for the signal to meet the trigger condition and then capture it.

The OWON PDS5022S allows you to save up to four waveforms:

To save: Press SAVE/RCL to bring up the menu. Select the source using F1, choose a location (A, B, C, or D) with F2, and press F3 to save.

To recall: Press SAVE/RCL. Use F2 to select the location (A, B, C, or D). Press F4 to turn CH(X) to ON, which will display the stored waveform.

If the OWON PDS5022S shows a black screen, perform the following troubleshooting:

1. Check if the power connection is properly secured.

2. Confirm the power switch is pushed down into the designated position.

3. Restart the OWON PDS5022S.

If the waveform is unstable on the OWON PDS5022S, check the following:

1. Ensure the Source in the TRIG MODE menu matches the channel being used.

2. Verify the trigger Type is set correctly (e.g., Edge for common signals, Video for video signals).

3. Try changing the trigger coupling to High Frequency Suppress or Low Frequency Suppress to reduce interference.

To charge the lithium battery on the OWON PDS5022S, please charge it for 12 hours. The OWON PDS5022S should be turned on during the charging process. A fully charged battery can supply power for approximately 4 hours.
