OWON PDS6042S (01) PDF Document

To verify the normal operation of your OWON PDS6042S, follow these steps:

Step 1. Connect the instrument to power and press the power switch button. After the instrument completes its self-check, press the UTILITY button, access the FUNCTION menu, and select Recall Factory to reset the settings.

Step 2. Set the switch on your oscilloscope probe to 10X and connect it to the CH1 input BNC. Tighten the probe by rotating it to the right.

Step 3. Connect the probe tip and ground clamp to the probe compensator connector.

Step 4. Press the AUTO SET button. A square wave with 1 KHz frequency and 5V peak-to-peak value should appear on the screen in several seconds. You can repeat this process for CH2.

Proper compensation is required to match the probe with the input channel of the OWON PDS6042S. Perform the following steps:

Step 1. Set the attenuation coefficient in the menu to 10X and the probe switch to 10X. Connect the probe to the CH1 channel.

Step 2. Connect the probe tip to the probe compensator signal connector and the reference wire clamp to the ground wire connector, then press the AUTOSET button.

Step 3. Observe the displayed waveform. If it is overcompensated or undercompensated, adjust the probe until a correct square wave is achieved.

To ensure accurate vertical scale readings on the OWON PDS6042S, the menu setting must match the physical switch on the probe. Press the function menu button for the channel being used, then push the menu selection button corresponding to the probe to cycle through 1X, 10X, 100X, or 1000X until the value matches your probe’s physical switch setting. Note that when the switch is set to 1X, the bandwidth of the OWON PDS6042S is limited to 5MHz.

Self-calibration optimizes the OWON PDS6042S for accurate measurements. It must be executed if the ambient temperature changes by 5 degrees Celsius or more. Perform the following steps:

Step 1. Disconnect all probes and wires from the input connectors.

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

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

Step 4. Confirm the operation when the prompt appears. Ensure no contact is made with the input channels until the calibration is complete.

The OWON PDS6042S supports additive and subtraction operations between channels. Press the MATH MENU button to access the WAVE MATH menu. You can then choose from the following operations:

To use the FFT function on the OWON PDS6042S, ensure the horizontal menu is set to main timebase and not window mode. Press the MATH MENU, then select FFT. Use the function menu to select your source (CH1 or CH2), window type (Rectangle, Blackman, Hanning, or Hamming), display format (dB or Vrms), and zoom multiple.

The OWON PDS6042S can store up to four waveforms. To save a waveform, press the SAVE/RCL button to open the WAVE SAVE menu. Select the source (CH1, CH2, or MATH) using F1, assign a storage location (A, B, C, or D) using F2, and press F3 to save. To recall a waveform, enter the same menu, select the location using F2, and set the CH(X) to ON using F4.

The OWON PDS6042S can display four automatic measurements simultaneously. Press the MEASURE button to activate the menu. Use F1 to toggle between Source and Type. Select your source channel and the measurement type you wish to perform (e.g., Freq, Pk-Pk, Mean, RMS). The results will appear in the reading window.

To activate cursors on the OWON PDS6042S, press the CURSOR button. You can choose between Voltage or Time types. When Voltage is selected, horizontal lines appear for measurements. When Time is selected, vertical lines appear. Use the position control knobs to adjust the cursors and observe the delta and position values on the display.

Autoscale is a quick way to set up the OWON PDS6042S for an incoming signal. By pressing the Autoscale button and selecting ON, the instrument automatically adjusts the trigger, voltage scale, and time scale. You can choose to adjust only vertical, only horizontal, or both scales (HORI-VERT) via the mode settings.

If the waveform is unstable on your OWON PDS6042S, try these steps:

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

2. Ensure the trigger Type (Edge or Video) is appropriate for your signal.

3. Adjust the trigger coupling to use high or low frequency suppression to smooth out interference.

To charge the battery of the OWON PDS6042S, plug in the instrument and leave it turned on for 12 hours. A fully charged battery provides approximately 4 hours of operation. Battery level is indicated by icons on the top of the display.
