Quick Guide

This chapter introduces basics of using the UPO7000L series oscilloscope for the first time, including the front panel, rear panels, and user interface.

General Inspection
It is recommended to inspect the instrument by following the steps below before using the UPO7000L series oscilloscope.

1. Check for transport damage
   If the packaging carton and the plastic foam cushions damage. If significant damage is found, please contact the UNI-T distributor.
2. Check accessories
   Refer to the appendix for the list of included accessories. If any accessories are missing or damaged, please contact the UNI-T distributor.
3. Machine inspection
   Examine the instrument for any visible damage, operational issues, or failures during the functionality test. If problems are detected, contact the UNI-T distributor.

If the instrument is damaged during shipping, retain the packaging materials and notify both the transportation department and the UNI-T distributor. UNI-T will arrange for maintenance or replacement as necessary.

Before Use

To perform a quick verification of the instrument’s normal operations, follow the steps below.

Connecting Power Supply
The power supply voltage ranges from 100VAC to 240VAC, with a frequency range of 50Hz to 60Hz. Use the assembled power cable or another power cable that meets the local country standards to connect the oscilloscope. When the power switch on the rear panel is disabled, the power soft indicator in the left bottom on the rear panel lights up orange, press the
soft power key to turn on the oscilloscope; when the power switch on the rear panel is enabled, the oscilloscope will automatically power on.

Boot-up Check
Press the soft power key to turn on the oscilloscope, the indicator will change from orange to blue. The oscilloscope will show a boot animation before entering the normal interface.

Connecting Probe
Use the assembled probe, connect BNC of probe to CH1 BNC on the oscilloscope, connect the probe tip connects to “Probe Compensation Signal Connection Sheet”, and connect the ground alligator clip to the “Ground Terminal” of probe compensation signal connection sheet, as shown in the following figure. The probe compensation signal connection sheet outputs an amplitude of approximately 3Vpp and a default frequency of 1kHz.

Function Inspection
Press the Autoset (Automatic Setting) icon, a square wave with an amplitude of approximately 3Vpp and a frequency of 1kHz will appear on the screen. Repeat step 3 to check all channels. If the displayed square wave shape does not match the one shown in the figure above, proceed to the next step “Probe Compensation.”

Probe Compensation
When the probe is connected to any input channel for the first time, this step may need to be adjusted to match the probe and the input channel. Uncompensated probes can lead to measurement errors or inaccuracies. Please follow the steps below to calibrate probe compensation.

1. Set the attenuation coefficient in the probe menu to 10x and ensure the probe switch is set to 10x. Connect the probe to CH1 on the oscilloscope. If using the probe’s hook head, ensure it makes stable contact with the probe.
2. Connect the probe tip to the “Probe Compensation Signal Connection Sheet” and the ground alligator clip to the “Ground Terminal” of the “Probe Compensation Signal Connection Sheet.” Open CH1 and press the Autoset icon.

View the displayed waveform, as shown in the following figure.

If the displayed waveform appears as “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 the risk of electric shock when using the probe to measure high voltage, ensure that the probe insulation is intact and avoid physical contact with any metallic parts of the probe.

Troubleshooting

This section provides a list of potential faults and troubleshooting methods that may occur while using the oscilloscope. If you encounter any of these issues, please follow the corresponding steps to resolve them. If the problem persists, contact UNI-T and provide the equipment information for your device.

1. If the oscilloscope remains on a black screen without any display when press the soft power button.
   • Check if the power plug is properly connected and the power supply is normal.
   • Check whether the power switch of the oscilloscope is turned on. Once the switch is on, the power soft switch button on the front panel should display a red light. After pressing the start soft switch, the soft power switch button will turn blue, and the oscilloscope will emit a startup sound.
   • If a sound is heard, it indicates that the oscilloscope has booted up normally.
   • If the product still does not work properly, contact the UNI-T Service Center for assistance.
2. After signal acquisition, the waveform of the signal does not appear on the screen.
   • Check whether probe and DUT are connected properly.
   • Check whether the signal connecting line is connected to analog channel.
   • Check whether the analog input terminal of the signal matches the channel that is currently selected on the oscilloscope.
   • Connect the probe tip to the probe compensation signal connector on the front panel of the oscilloscope and verify whether the probe is functioning properly.
   • Check if the device under test is generating a signal. The user can connect the signal-generating channel to the problematic channel to help diagnose the issue.
   • Click Autoset to allow the oscilloscope to automatically reacquire the signal.
3. The measured voltage amplitude value is 10 times larger or 10 times smaller than the actual value.
   • Check whether the probe attenuation setting on the oscilloscope matches the attenuation factor of the probe being used.
4. There is a waveform display, but it is unstable.
   • Check the trigger settings in the trigger menu to ensure they match the actual signal input channel.
   • Check the trigger type: general signals should typically use the “Edge” trigger. The waveform will display stably only if the trigger mode is set correctly.
   • Try changing the trigger coupling to HF rejection or LF rejection to filter out high-frequency or low-frequency noise that may be interfering with the trigger.
5. Waveform refresh is very slow.
   • Check whether the acquisition method is set to “Average” and if the average times are large.
   • To accelerate the refresh speed, the user can reduce the number of averaging times or select other acquisition methods.

Maintenance and Cleaning

General Maintenance
Keep the probe and its accessories away from the direct sunlight.
Caution: Avoid contact with sprays, liquids, or solvents to prevent probe damage.

Cleaning
Check the probe frequently according to the operating condition. Follow these steps to clean the external surface of the probe:
Use a soft cloth to remove dust from the probe.
Disconnect the power supply and clean the probe with mild detergent or water.
Do not use abrasive or chemical cleaners, as they may damage the probe.

Warning: Please confirm that the instrument is completely dry before use, to avoid electrical shorts or even personal injury caused by moisture.
