3. Getting Started Guide
This chapter introduces on using the oscilloscope for the first time, the front and rear panels, the user
interface, as well as the built-in help system.
3.1 General Inspection
It is recommended to inspect the instrument follow the steps below before using the MSO/UPO2000 series
for the first time.
(1) 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.
(2) Check Attachment
Please check 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.
(3) 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.
3.2 Before Use
To perform a quick verification of the instrument's normal operations, please follow the steps below:
(1) Connect to the Power Supply
The power supply voltage range is from 100 VAC to 240 VAC, the frequency range is 45 Hz to 440 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. Turn on the power button, which on the back of the
oscilloscope. The soft power button in the front of the oscilloscope should be on red.
(2) Boot Check
Press the soft power button and the light should change to green. The oscilloscope will show a
boot animation, and then enter the normal interface.
(3) Connect Probe
Use probe in the attachment and connect it BNC port to the channel 1 BNC port of the oscilloscope.
Connect the probe’s main alligator clip to the “Compensating signal port” and the ground clip is
connected to the “Ground terminal” shown below. The output of the compensating signal should be
amplitude 3 Vpp, default frequency is 1 kHz.

Quick Start Guide MSO/UPO2000 Series

Instruments.uni-trend.com
Figure 1 Compensating signal and Ground terminal
(4) Function Check
Press the AUTO key, a 3 Vpp 1 kHz square wave should appear. Repeat step 3 for all channels. If the output
is not a square wave with the above descriptions, please perform the probe compensation step 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 in order
to match the probe and the input channel. Probes that are not compensated may lead to measurement
errors or mistake. Please follow the following steps:
①Set the attenuation coefficient in the probe menu and the switch on the probe to 10x, and connect the
probe to CH1. Make sure the probe’s connector is properly connected with 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.
②View the displayed waveform, as shown in Figure 2.
Excessive Compensation Correct Compensation Insufficient Compensation
Figure 2 Compensating Calibration of Probe
③If the displayed waveform is look 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.

10. Troubleshooting
(1) When press the button, the oscilloscope is blank screen.
a. Check whether the power is correctly connected, power supply is normal or not.
b. Check whether the power switch is really turned on. The soft power switch button should light in
green when the instrument is normal boot. And it should have 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 device returns to normal, it means
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.
(2) After signal acquisition, signal of waveform does not appear on the screen.
a. Check whether 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 signal of information source.
e. Plug out the input signal, 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.
(3) 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.
(4) 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: general signal should use “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, in order to filter out
the high-frequency or low-frequency noise that interferes with the trigger.
(5) No display after pressing Run/Stop button
a. Check whether the mode at the trigger panel (TRIGGER) is on “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 AUTO button could automatically finish the above setting.
(6) 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.
