This chapter is to introduce 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 UPO1000 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) Connecting to the Power Supply

AC power specification of UPO1000 series digital storage oscilloscope refers to Connecting Power

Supply section. Use the assembled power line or other power line that meets the local country

standards to connect the oscilloscope. The power soft indicator in the left bottom on front

panel is extinguished and this soft switch key is no-effect when the power switch on rear panel is not

opened. The power soft indicator in the left bottom on front panel is illuminated with red and

then press the soft switch key to enable the oscilloscope.

(2) Boot Check

Press the soft power key and the indicator should change from red to green. The oscilloscope

will show a boot animation, and then enter the normal interface.

(3) Connecting Probe

Use BNC of the port to connect to BNC of CH1 of the oscilloscope. Connecting the probe to the “probe

compensation signal connection clip” and connecting the ground alligator clip to the “ground terminal”

under the “probe compensation signal connection clip”. The output of probe compensation signal

connection clip is the amplitude about 3Vpp and the frequency defaults to 1 kHz.

Figure 4-1 Probe Compensation Signal Connection Clip and Ground Terminal

(4) Function Check

Press the AUTO key, a 3 Vpp, 1 kHz square wave should appear on the screen. 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 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.

Set the attenuation coefficient in the probe menu to 10x and the switch of the probe at 10x, and

connecting the probe of the oscilloscope to CH1. If use the probe’s hook head, make sure it stably

touch to the probe. Connecting the probe to the “probe compensation signal connection clip” and

connecting the ground alligator clip to the “ground terminal” under the “probe compensation signal

connection clip”. Open CH1 and press the AUTO key.

View the displayed waveform, as shown in Figure 4-2.

Excessive Compensation Correct Compensation Insufficient Compensation

Figure 4-2 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.
