Getting Started Guide

This chapter introduces using the oscilloscope for the first time, the front and rear panels, the user interface, as well as the built-in help system.

General Inspection

It is recommended to inspect the instrument by following the steps below before using the MSO/UPO3000E series for the first time.

Check for Damages caused by Transport
- If the packaging carton or the foam plastic cushions are severely damaged, please contact the UNI-T distributor of this product immediately.
Check Attachment
- Please check the appendix for the list of accessories. If any of the accessories are missing or damaged, please contact UNI-T or local distributors of this product.
Machine Inspection
- If the instrument appears to be damaged, not working properly, or has failed the functionality test, please contact UNI-T or local distributors of this product.
- 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.

Connect to the Power Supply
- The power supply voltage range is from 100 VAC to 240 VAC, the frequency range is 50 Hz to 60 Hz. Connect the oscilloscope to the power supply line that came with the oscilloscope or any power supply line that meets the local country standards.
- If the power switch on the rear panel is not turned on, the indicator of the power soft button on the left corner of the front panel will be extinguished and no function.
- If the power switch on the rear panel is turned on, the indicator of the power soft button on the left corner of the front panel will be red, press this button to boot up the instrument.
Boot-up Check
- Press the soft power buttonand the light should change to green. The oscilloscope will show a boot animation, and then enter the normal interface.
Connect Probe
- Use the probe’s BNC port to connect to the channel 1 BNC port of the oscilloscope. Connect the probe to the “Compensating signal port” and the ground clip is connected to the “Ground terminal” below the compensating signal port as shown in Figure 1.
- The output of the compensating signal should be amplitude 3 Vpp, default frequency is 1 kHz
Function Check
- Press the AUTO key, and a 3 Vpp 1 kHz square wave should appear. Repeat step 3 to check all channels.

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.

If need to adjust the probe compensation, please follow the following steps:

Set the attenuation coefficient in the probe menu and the switch on the probe 10x, and connect the probe to CH1. Make sure the probe’s connector is properly connected to the oscilloscope.
Connect the probe’s main clip and ground clip to the oscilloscope’s compensating signal and ground terminal respectively. Open CH1 and press the AUTO button.

View the displayed waveform, as shown in Figure 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 blank 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 turned on. The soft power switch button should light in green when the instrument is a normal boot. And it should have a relay sound.
- c. If there is a relay sound, it indicates that the oscilloscope starts normally.
- Try the following steps: press the DEFAULT key, then press F1, if the device returns to normal, it means the backlight brightness is set too low.
- d. After completing the above steps, restart the oscilloscope.
- e. If the instrument still cannot work, please contact UNI-T.
After signal acquisition, a signal of the waveform does not appear on the screen
- a. Check whether the BNC port is connected properly.
- b. Check whether the signal output channel has turned on.
- c. Check whether the input signal channel has turned on.
- d. Check whether has DC displacement in the signal of the information source.
- e. Plug out the input signal, and check whether the baseline is in the screen range (if not, please perform auto-calibration.)
- f. If the instrument still cannot work, please contact UNI-T.
The measured voltage amplitude value is 10 times larger or smaller than the actual value: Check the channel probe attenuation coefficient setting is consistent with the used probe attenuation rate.
There is a waveform display but not stable
- a. Check the trigger source in the trigger menu and confirm that it matches the input channel of the actual signal.
- b. Check the trigger type: the general signal should use the “Edge” trigger. The waveform can display stably only the proper trigger type is used.
- c. Change the trigger coupling setting to high-frequency or low-frequency reject, to filter out the high-frequency or low-frequency noise that interferes with the trigger.
No display after pressing the Run/Stop button
- a. Check whether the mode at the trigger panel (TRIGGER) 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 trigger mode to Auto.
- c. Press the AUTO button could automatically finish the above setting.
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 release time is large.
- d. Check whether the trigger is normal and the current time base is slow.
- e. All the preceding causes slow refreshing of waveforms. Users can restore the factory settings so that the waveforms can be refreshed normally.
