Chapter 1 Getting Started Guide

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

1.1 General Inspection

It is recommended to follow the steps below before using the UPO3000E
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

are missing or damaged, please contact UNI-T distributor or local office
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 distributor or local office
of this product.
If the equipment is damaged due to shipping, please keep the packaging
and notify both the transportation department and the UNI-T distributor,
UNI-T will arrange maintenance or replacement.

1.2 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 45Hz to 440Hz. Connect the oscilloscope to the power supply
cord that came with the oscilloscope or any power supply cord that meets
the host country standards. Turn the power button on the back of the
oscilloscope to ON. Now the soft power button
oscilloscope should be lit green.

(2) Boot Check
Press the soft power button
oscilloscope then will show a boot animation, and it will enter the normal
interface afterwards.
(3) Connect Probe
Take the probe found in the attachment and connect its BNC terminal to
the BNC of channel 1 of the oscilloscope. Connect the probe to the
"probe compensation signal connector" and connect the probe' s ground
alligator clip to the "ground terminal" shown below. The output of the
probe compensation signal connector should be a 3Vp-p square wave,
with a 1 kHz frequency.

(4) Function Check
Press the AUTO key, a 3Vp-p 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 required in order to match the probe and the input channel. An
uncompensated probe may cause a measurement error. To adjust the probe
compensation, please follow the following steps:
1 . Set the probe menu attenuation coef ficient to 10×, and set the switch on
the probe to 10x then connect the probe to CH1. Make sure the probe's
hooks is properly connected with the oscilloscope. Connect the probe to
in the front of the
the "probe compensation signal connector" and connect the probe's ground
alligator clip to the "ground terminal". Turn on CH1 and press the AUTO button.
