UNI-T UT804 Oscilloscope F.A.Q.

How do I set up the UNI-T UT804 Oscilloscope for the first time?

To set up your UNI-T UT804 Oscilloscope for the first time, connect the power cord to an electrical outlet, attach the probes to the input channels, and follow the on-screen instructions to configure language, time, and date settings. Make sure to perform a self-calibration by following the manual instructions.

What should I do if the UNI-T UT804 does not power on?

Ensure that the power cable is securely connected to both the oscilloscope and the power outlet. Check the outlet for power and try using a different power cord if available. If the device still does not power on, contact UNI-T support as there might be an internal issue.

How can I capture and store waveform data on the UNI-T UT804?

To capture and store waveform data, press the 'Save' button on the front panel. You can choose to save data to the internal memory or to an external USB drive. Ensure that the USB drive is correctly formatted and inserted into the USB port.

What maintenance is required to keep the UNI-T UT804 in optimal condition?

Regularly clean the oscilloscope's exterior with a soft, dry cloth. Avoid using solvents or abrasive cleaners. Periodically run the self-calibration function and check for firmware updates from UNI-T. Store the oscilloscope in a clean and dry environment when not in use.

How do I troubleshoot inaccurate measurements on the UNI-T UT804?

First, ensure that the probes are properly connected and calibrated. Check the probe compensation adjustment and perform a self-calibration. Verify that the oscilloscope settings match the test parameters. If the issue persists, refer to the user manual for further diagnostics or contact support.

Can the UNI-T UT804 measure frequency and how is it done?

Yes, the UNI-T UT804 can measure frequency. Connect the probe to the signal source, set the vertical and horizontal scales appropriately, and use the 'Measure' function to select 'Frequency'. The frequency value will be displayed on the screen.

What is the procedure to update the firmware on the UNI-T UT804?

Download the latest firmware from the UNI-T website to a USB drive. Insert the USB drive into the oscilloscope's USB port. Navigate to the 'Utility' menu, select 'Firmware Update', and follow the on-screen instructions to complete the update.

How do I adjust the vertical scale on the UNI-T UT804?

Use the vertical scale knob located on the front panel corresponding to the channel you are using. Rotate the knob to increase or decrease the vertical scale as needed for better visibility of the waveform.

Why is the waveform display flickering on my UNI-T UT804?

Ensure that the oscilloscope is properly grounded and that there is no electromagnetic interference. Adjust the trigger level and type to stabilize the waveform. If flickering persists, try reducing the ambient light or adjusting the display settings.

How can I use the UNI-T UT804 to perform a continuity test?

While the UNI-T UT804 primarily functions as an oscilloscope, you can perform basic continuity tests using the multimeter function. Connect the probes to the test points and select the continuity test mode; a beep will sound if continuity is detected.
