Chapter I Introduction
This chapter introduces what users should pay attention to, front & rear panels, user
interface and instruction of built-in system when using UTD 2000 series DSO first time.
1.1 General Inspection
After purchasing a new UTD2000 DSO, we recommend you to inspect the instrument
according to the following steps.
(1) Inspect whether there are damages caused by transportation
In case of severe damages to packing box or foamed plastic mat, you should replace
immediately.
(2) Accessories inspection
For provided accessories details, description has been made in annex A “Accessories” of
this user manual. Please check whether there are shortages in the accessories. If you
found shortage or damages of accessories, please contact the UNI-T distributors
distributing the product or local offices of UNI-T.
(3) Check the complete instrument
In case of damages to the appearance of instrument, abnormal operation or failure to pass
the performance tests, please contact the UNI-T product distributors or local UNI-T offices.
If the instrument is damaged due to transportation, please pay attention to keeping the
package, notify transportation department and UNI-T product distributors and UNI-T will
make arrangement for repair or replacement.
1.2 Function Inspection
Conduct a fast function inspection to verify whether the instrument is in normal operation.
Please take the steps as follows:
(1) Power on:
The power supply voltage range is from 100 VAC to 240 VAC, the frequency range is
50/60Hz. Connect the oscilloscope to the power supply line that comes with the
oscilloscope or any power supply line that meets the host country standards. Press the
power switch button on the top of the oscilloscope.
(2) Switch on the instrument and Check:
Press the power switch button , the oscilloscope then will show a boot animation, and it
will enter the normal interface afterwards.
(3) DSO accessing to signal
Connect the probe BNC terminal to the BNC of channel 1 of DSO, connect the probe to
“Probe Compensation Signal Tip”, connect the alligator clip of probe to the “Ground
Terminal”. The output of the probe compensation signal tip is: the range is about 3Vpp, the

UTD2000 Series User Manual
12
frequency defaults at 1kHz.
(4) Function Check
Press AUTO (auto setting) button, square wave appears on the display screen, the wave
range is about 3Vpp and the frequency is 1kHz. Go back to step 3 and check other
channels in a same way. If the actual displayed waveform is different from above figure,
please go to next step “Probe Compensation”.
(5) Probe Compensation
When connecting the probe with any input channel for the first time, it is required to make
adjustment for this item, matching the probe with input channel. Probe without being
compensated and corrected will lead to measurement error or mistake. In case of
adjustment of probe compensation, follow the following steps:
Set the probe menu attenuation coefficient as 10×, place the switch on the probe
at 10×and connect DSO probe with CH1. If hook-shape head of probe is used,
please make sure that it contacts the probe. Connect the probe to the probe
compensator of DSO, connect the grounding clamp to the “Grounding terminal” of
probe compensator, turn on CH1 and press AUTO.
Observe displayed waveform
Figure 1-5 Probe Compensation and Correction
If screen displays “under-compensation” or “over-compensation” for waveform as
shown in above figures, use screwdriver with nonmetal handle to adjust the
variable capacitance on the probe until screen displays “correct compensation” for
waveform as shown in the above figure.

Warning: In order to avoid electric shock when measuring high voltage with probe,
please ensure that the insulation lead of the probe is in good condition and do not
contact the metal part of the probe when connecting high pressure power supply.

1.4 Automatic Settings of Waveform Display
UTD2000 series DSO has automatic setting function. According to input signals,
automatically adjust the vertical deflection factor, scanning time base and trigger mode until
the most appropriate waveform is displayed. For automatic setting application, the
frequency of the measured signal is required to be ≥20Hz.
Apply automatic setting:
(1) Connect measured signal to signal input channel.
(2) Press AUTO key. DSO will automatically set its vertical deflection factor, scanning time
base and trigger mode. If further careful observation is required, adjustment can be
conducted again after automatic settings until the waveform display reaches required
optimum effect.

(1) Vertical POSITION: vertical position knob, user can change the current vertical position
of channel waveform, the vertical position value will display on the
baseline cursor area. Press this knob to get the dispayed channel position back to the
vertical center.
If the coupling mode of channel is DC, user can fast measure the DC component
of signal by observing the difference between waveform and signal ground.
If the coupling mode of channel is AC, the DC component in the signal will be
filtered, which helps to displayAC component of signal with higher sensitivity.
(2) Vertical SCALE: Change vertical setting and observe the change of status information.
User can confirm any change of vertical scale level by the information displayed on the
status bar. Rotate the vertical scale knob to change the vertical scale level of
“VOLTS/DIV”, and then the scale level of channel on the stauts bar will be changed
accordingly. Press CH1, CH2, MATH to display operation menu, symbols, waveform
and scale level status of corresponding channels. Double click CH1, CH2, MATH to
turn off the channel.
1.6 Introduction to the Horizontal System
