   A diagram shows a probe with a tip and a ground clip connected to a compensating signal connection clip and a ground terminal.
4. Function Check
   Press the AUTO key, a square wave (amplitude 3 Vpp, frequency 1 kHz) should appear on the screen. Repeat step 3 to check all channels. If the square waveform display does not match the one shown above, please follow the 'Probe Compensation' procedure described in the next section.
5. Probe Compensation
   When the probe is connected to any input channel for the first time, this step might be adjusted to match the probe and the input channel. Probes that are not compensated may lead to measurement errors or mistakes. Please follow the following steps to adjust the probe compensation:
   
   • Set the probe attenuation ratio in the probe menu to 10x. Connect the oscilloscope probe to C1. If using the probe's hook tip, ensure it makes stable contact. Connecting the probe to the "Probe Compensation Signal Connection Clip" of the oscilloscope and connect the ground alligator clip to the ground terminal of the probe compensating signal connection clip. Open C1 and press the Autoset key.
   View the displayed waveform, as shown in the following figure 2.
   
   Figure 2 Probe Compensation Calibration
   Illustrations show three waveforms: Excessive Compensation, Correct Compensation, and Insufficient Compensation.
   If the displayed waveform resembles the above “Insufficient Compensation” or “Excessive Compensation”, use a non-metallic screwdriver to adjust the probe's variable capacitance until the display matches the "Correct compensation" waveform.
   Note: The probe type is UT-P07A and UT-P08A. When connected to the oscilloscope, the probe ratio will be automatically identified as X10.
   Warning: To avoid electric shock when using the probe to measure high voltage, please ensure that the probe insulation is in good condition and avoid physical contact with any metallic part of the probe.

6. Troubleshooting

If the oscilloscope remains on a black screen without any display when pressing the power soft key:

• Check if the power plug is properly connected and the power supply is normal.
• Check if the power switch is turned on. If the power switch is turned on, the power soft key on the front panel should be green. When the power soft key is enabled, the power soft key should be blue, and the oscilloscope will make an active sound. There should be a normal relay rattle when the soft switch key is pressed.
• If the relay has sound, it indicates that the oscilloscope is normal boot-up. Press the Default key and press the “Yes” key; if the oscilloscope returns to normal, it indicates that the backlight brightness is set too low.
• Restart the oscilloscope after completing the above steps.
• If the product still does not work properly, contact the UNI-T Service Center for assistance.

After signal acquisition, if the waveform of the signal does not appear on the screen:

• Check whether the probe and DUT are connected properly.
• Check whether the signal output channel is open.
• Check whether the signal connecting line is connected to the analog channel.
• Check whether the signal source has DC offset.
• Plug out the connected signal, to check whether the base line is within the screen range (If not, please perform self-calibration).
• If the product still does not work properly, contact the UNI-T Service Center for assistance.

The measured voltage amplitude value is 10 times larger or 10 times smaller than the actual value:

• Check whether the channel probe attenuation ratio settings are consistent with the used probe attenuation rate.

There is a waveform display but not stable:

• Check the trigger settings in the trigger menu whether they are consistent with the actual signal input channel.
• Check the trigger type: the general signals should use "Edge" trigger. The waveform can only be displayed stably if the trigger mode is set correctly.
• Try to change trigger coupling to HF rejection or LF rejection, to filter out the high-frequency or low-frequency noise that interferes with the trigger.

No waveform display after pressing the Run/Stop key:

• Check whether the trigger mode is set to "Normal" or "Single" and verify if the trigger level exceeds the waveform range.
• If the trigger mode is normal or single and the trigger level is in the center, set the trigger mode to AUTO.
• Press the Autoset key to automatically complete the above settings.

Waveform refresh is very slow:

• Check whether the acquisition method is set to "Average" and if the average times are large.
• Check whether the memory depth is maximum.
• Check whether the trigger holdoff is large.
• Check whether it is normal trigger and is slow time base.
• All the above will lead to slow waveform refresh; it is recommended to restore the factory settings, then the waveform can be refreshed normally.
