UNI-T UT801 Oscilloscope F.A.Q.

How do I set up the UNI-T UT801 Oscilloscope for the first time?

To set up the UNI-T UT801, connect the oscilloscope to a power source and turn it on. Connect the probes to the channels you intend to use. Calibrate the probes by connecting them to the probe compensation terminals and adjusting until the waveform is a clean square wave.

What should I do if the screen of the UNI-T UT801 is not displaying any signal?

Ensure that the probes are correctly connected to the oscilloscope and the test points. Check that the channel is turned on and the vertical and horizontal scales are correctly set. Verify that the trigger mode is appropriately configured.

How can I save waveform data on the UNI-T UT801?

To save waveform data, use the USB interface to connect to a computer. Use the provided software to capture and save the waveform data onto your PC. Ensure that the oscilloscope is set to the desired settings before capturing the data.

Why is the waveform display on my UNI-T UT801 oscilloscope distorted?

Distorted waveforms can result from improper probe calibration or incorrect vertical/horizontal settings. Re-calibrate the probe and adjust the oscilloscope settings. Also, check for interference or noise in the signal source.

How do I perform a self-calibration on the UNI-T UT801?

To perform a self-calibration, ensure that the oscilloscope is warmed up for at least 20 minutes. Navigate to the calibration menu and follow the on-screen instructions to complete the self-calibration process.

What is the maximum input voltage for the UNI-T UT801 oscilloscope?

The maximum input voltage for the UNI-T UT801 oscilloscope is 400V (DC + AC Peak). Exceeding this voltage can damage the oscilloscope and pose a safety risk.

How can I check if the probes on my UNI-T UT801 are functioning correctly?

Connect the probe to the calibration signal output on the oscilloscope. A stable square wave should be displayed. If not, adjust the probe compensation and ensure the probe is functioning correctly.

Can the UNI-T UT801 measure frequency accurately and how?

Yes, the UNI-T UT801 can measure frequency accurately. Connect the signal to a channel, and use the frequency measurement function by selecting 'Measure' and choosing 'Frequency' from the menu. Ensure the signal is stable for accurate measurement.

What is the best way to clean and maintain the UNI-T UT801?

To clean the oscilloscope, use a soft, damp cloth to wipe the exterior. Avoid using chemicals or solvents that may damage the surface. Regularly inspect and clean the probe tips and connectors to maintain optimal performance.

How do I update the firmware on my UNI-T UT801?

To update the firmware, download the latest version from the official UNI-T website. Connect the oscilloscope to your computer via USB, then use the software provided to install the firmware update. Follow the on-screen instructions carefully.
