    What to do if the UNI-T UTD2000CEX-II oscilloscope screen is black after pressing the power button?
    • A
      Alexis HoldenAug 2, 2025
      If your UNI-T Test Equipment oscilloscope screen remains black after pressing the power button, try the following: * Ensure the power supply is properly connected. * Verify the power switch on the back of the oscilloscope is on, then press the front panel power key to check for a green light. * If you hear a sound, press the DEFAULT key, followed by the F1 key. If the device returns to normal, the backlight brightness was likely too low. * Restart the oscilloscope after completing these steps.

    Why is the waveform not stable on my UNI-T Test Equipment oscilloscope?
    • L
      lauraloveAug 7, 2025
      If the waveform on your UNI-T Test Equipment oscilloscope isn't stable, consider these possible solutions: * Check the trigger source in the trigger menu to ensure it matches the signal and channel you are using. * Verify the trigger type. Normal signals should use edge trigger mode. Setting the correct trigger mode is essential for a stable waveform. * Adjust the trigger coupling to high or low frequency to suppress or eliminate noise caused by interference.

    What to do if pressing RUN/STOP key on UNI-T UTD2000CEX-II displays no waveform?

      If pressing the RUN/STOP key on your UNI-T Test Equipment results in no waveform being displayed, check the following: * Verify that the trigger method in the trigger menu is not set to normal and that the trigger level does not exceed the waveform range. If it does, center the trigger level or set the trigger mode to auto using the AUTO key. * Press the AUTO button to apply the above settings.

    What to do if waveform doesn't appear on UNI-T UTD2000CEX-II display after signal acquisition?
    • J
      James FrederickAug 17, 2025
      If a waveform does not appear on the display of your UNI-T Test Equipment after signal acquisition, check the following: * Ensure the probe is correctly connected to the signal test point. * Verify the signal line is connected to the analog channel input. * Confirm the input signal of the analog channel and ensure that the channel is open. * Make sure the probe is connected to the compensation piece and that the probe itself is working correctly. * Check for the presence of a signal to be detected. * Press the AUTO button to re-acquire the signal.

    Why is the measured amplitude on my UNI-T Test Equipment 10 times larger or smaller than expected?
    • P
      pachecofrankAug 22, 2025
      If the measured amplitude value on your UNI-T Test Equipment is 10 times larger or smaller than the actual value, ensure that the probe attenuation coefficient matches the attenuation of the probe being used.

    How to fix a slow waveform refresh rate on UNI-T Test Equipment?
    • G
      gibsondianaAug 27, 2025
      To address a slow waveform refresh rate on your UNI-T Test Equipment, check if the acquisition mode is set to average and if the number of averages is too high. You can increase the refresh rate by reducing the average times or selecting other methods such as normal sampling.
