  - If the equipment is damaged due to shipping, please keep the packaging and notify both the transportation department and UNI-T distributors, UNI-T will arrange maintenance or replacement.

Before Use

To perform a quick verification of the instrument’s normal operations, please follow the steps below.
1. Connecting to the Power Supply
  - AC power specification of UPO1000 series digital storage oscilloscope refers to the Connecting Power Supply section. Use the assembled power line or other power line that meets the local country standards to connect the oscilloscope.
  - The power soft indicator in the left bottom on the front panel is extinguished and this soft switch key has no effect when the power switch on the rear panel is not opened.
  - The power soft indicatorin the left bottom of the front panel is illuminated with red and then press the soft switch key to enable the oscilloscope.
2. Boot Check
  - Press the soft power keyand the indicator should change from red to green. The oscilloscope will show a boot animation, and then enter the normal interface.
3. Connecting Probe
  - Use the BNC of the port to connect to the BNC of CH1 of the oscilloscope.
  - Connecting the probe to the “probe compensation signal connection clip” and connecting the ground alligator clip to the “ground terminal” under the “probe compensation signal connection clip”.
  - The output of the probe compensation signal connection clip is the amplitude about 3Vpp and the frequency defaults to 1 kHz.
4. Function Check
  - Press the AUTO key, and a 3 Vpp, 1 kHz square wave should appear on the screen. Repeat step 3 to check all channels.
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.
  - Set the attenuation coefficient in the probe menu to 10x and the switch of the probe to 10x, and connect the probe of the oscilloscope to CH1. If use the probe’s hook head, make sure it stably touches the probe.
  - Connecting the probe to the “probe compensation signal connection clip” and connecting the ground alligator clip to the “ground terminal” under the “probe compensation signal connection clip”. Open CH1 and press the AUTO key.
  - View the displayed waveform, as shown in Figure 4-2.
  - If the displayed waveform looks like 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.
  - 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.

Troubleshooting

When press the button, the oscilloscope is a black screen.
- a. Check whether the power is correctly connected and whether the power supply is normal or not.
- b. Check whether the power switch is really on, press the front panel power key, and confirm the green light and a relay sound are present.
- c. If there is a relay sound, it indicates that the oscilloscope starts normally. Try the following operations: press the DEFAULT key, then press F1, if the device returns to normal, it means the backlight brightness is too low.
- d. After completing the above steps, restart the oscilloscope.
- e. If you still cannot use this product normally, please contact UNI-T.

After signal acquisition, the waveform of the signal does not appear in the picture.
- a. Check whether the two ends of the BNC line are connected properly.
- b. Check whether the output channel of the signal source is opened.
- c. Check whether the input channel of the oscilloscope is opened.
- d. Check whether the signal in the signal source has a DC offset.
- e. Plug out the input signal, and check whether the baseline is in the center of the screen (if the baseline is not in the center of the screen, it should be self-calibration.)
- f. If you still cannot use this product normally, please contact UNI-T.
The measured voltage amplitude value is 10 times larger or 10 times smaller than the actual value: Check whether the channel probe attenuation coefficient settings are consistent with the used probe attenuation rate.
There is a waveform display but not stable.
- a. Check the trigger settings in the trigger menu whether is consistent with the actual signal input channel.
- b. Check the trigger type: general signals should use the “Edge” trigger. Only when the proper trigger type is used, the waveform can be displayed stably.
- c. 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.
- a. Check whether the trigger mode in the trigger menu is “Normal” or “Single” and whether the trigger level exceeds the waveform range.
- b. If it exceeds, set the trigger level to the middle or set the mode to “Auto”.
- c. The above settings can be completed automatically by pressing the AUTO key.
Waveform refresh is very slow.
- a. Check whether the acquisition method is average and the average times are large.
- b. Check whether the storage depth is the maximum.
- c. Check whether the trigger hold-off time is greater.
- d. Check whether the trigger is normal and the current time base is slow.
- e. All the above reasons will lead to a slow refresh of the waveform. It is recommended to restore the factory settings, and the waveform can be refreshed normally.
