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 terminal to the channel 1 BNC terminal of the
oscilloscope. Connect the probe’s main alligator clip to the “Compensating signal terminal” and the ground
clip is connected to the “Ground terminal” shown below. The output of the compensating signal should
be a 3 Vpp amplitude, default frequency is 1 kHz.
Figure 1 Compensating Signal and Ground Terminal
(4) Function Check
Press theAUTO key, a 3 Vpp 1 kHz square ware should appear. Repeat step 3 for all channels.
(5) Probe Compensation
When the probe is connected to any input channel for the first time, this step might be required 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:
Compensating signal terminal
Ground terminal

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 theAUTO button.
②View displayed waveforms
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 measuring high voltage using the probe, please ensure
that the probe insulation is in good condition and avoid physical contact with any metallic part of
the probe.

8. Remote Control
UPO1000CS series digital phosphor oscilloscope communicates with the computer through USB
interface andLAN interface to achieve remote control. Remote control is implemented based on the SCPI
(Standard Commands for Programmable Instruments) command set.
UPO1000CS series digital phosphor oscilloscope supports three remote control modes:
a. User-defined programming.
b. Use PC software (instrument manager).
c. Web Control.
9. Troubleshooting
(1) When press the soft power 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,press the front panel power key and confirm
green light and a relay sound is 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 device returns to normal, it means
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.
(2) After signal acquisition, waveform does not appear on display：
a. Check whether both ends of the BNC cable are connected properly.
b. Check whether the output channel of the signal source is open.
c. Check whether the oscilloscope access signal channel is open.

14 / 14
d. Check whether the signal in the signal source has a DC offset.
e. Remove the incoming signal and check whether the baseline is in screen range (if not, self-
calibration is required).
f. If you still cannot use this product normally, please contact UNI-T.
(3) The measured voltage amplitude value is 10 times larger or smaller than the actual value: Check
that the channel probe attenuation coefficient settings are consistent with the used probe attenuation
rate.
(4) There is a waveform displays 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 signals should use “Edge” trigger. Only when the proper trigger
type is used, the waveform can displayed stably.
c. Change the trigger coupling to high-frequency or low-frequency to filter out the high-frequency
or low-frequency noise that interferes with the trigger.
(5) No display after pressing RUN/STOP:
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 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.
