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.

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.
