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/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

Please check appendix for the list of accessories. If any of the accessories are missing or damaged, please

Quick Start Guide MSO/UPO3000E Series Oscilloscope

Instruments.uni-trend.com 8/ 17

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 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 power soft

button on the left corner on the front panel will be extinguished and no function. If the power switch

on the rear panel is turned on, the indicator of power soft button on the left corner on the front panel

will be on red, press this button to boot-up the instrument.

(2) Boot-up 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’s BNC port 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

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 to check all channels.

(5) Probe Compensation

When the probe is connected to any input channel for the first time, this step might be adjusted in order to

Compensating signal terminal

Ground terminal

Quick Start Guide MSO/UPO3000E Series Oscilloscope

Instruments.uni-trend.com 9/ 17

match the probe and the input channel. Probes that are not compensated may lead to measurement errors

or mistake. 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 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.

View the displayed waveform, as shown in Figure 2.

Excessive Compensation Correct Compensation Insufficient Compensation

Figure 2 Compensating Calibration of Probe

If 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.
