Introduction of UPO1000CS Series Digital Phosphor Oscilloscope UPO1000CS series contains the following 2 models. Model Analog Channels UPO1202CS 2 UPO1102CS 2 Bandwidth 200MHz 100MHz 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 UPO1000CS 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. 7 / 14 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 terminal to the channel 1 BNC terminal of the oscilloscope. Connect the probe's main alligator clip to the "Compensating signal terminal" and the ground clip is connected to the "Ground terminal" shown below. The output of the compensating signal should be a 3 Vpp amplitude, default frequency is 1 kHz. Compensating signal terminal Ground terminal Figure 1 Compensating Signal and Ground Terminal (4) Function Check Press the AUTO key, a 3 Vpp 1 kHz square ware should appear. Repeat step 3 for all channels. (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. Probes that are not compensated may lead to measurement errors or mistake. Please follow the following steps: 8 / 14 Set 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. View displayed waveforms 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 measuring high voltage using the probe, please ensure that the probe insulation is in good condition and avoid physical contact with any metallic part of the probe. 9 / 14 4.

Single page has no small circle, and two or more pages will have small circle display. Press F5 to turn pages. 8. Remote Control UPO1000CS series digital phosphor oscilloscope communicates with the computer through USB interface and LAN interface to achieve remote control. Remote control is implemented based on the SCPI (Standard Commands for Programmable Instruments) command set. UPO1000CS series digital phosphor oscilloscope supports three remote control modes: a. User-defined programming. b. Use PC software (instrument manager). c. Web Control. 9. Troubleshooting (1) When press the soft power button, the oscilloscope is blank screen a. Check whether the power is correctly connected, power supply is normal or not. b. Check whether the power switch is really turned on, press the front panel power key and confirm green light and a relay sound is present. c. If there is a relay sound, it indicates that the oscilloscope starts normally. Try the following operations: press the DEFAULT key, then press F1, if device returns to normal, it means backlight brightness is too low. d. After completing the above steps, restart the oscilloscope. e. If you still cannot use this product normally, please contact UNI-T. (2) After signal acquisition, waveform does not appear on display a. Check whether both ends of the BNC cable are connected properly. b. Check whether the output channel of the signal source is open. c. Check whether the oscilloscope access signal channel is open. 13 / 14 d. Check whether the signal in the signal source has a DC offset. e. Remove the incoming signal and check whether the baseline is in screen range (if not, self- calibration is required). f. If you still cannot use this product normally, please contact UNI-T. (3) The measured voltage amplitude value is 10 times larger or smaller than the actual value: Check that the channel probe attenuation coefficient settings are consistent with the used probe attenuation rate. (4) There is a waveform displays but not stable: a. Check the trigger source in the trigger menu and confirm that it matches the input channel of the actual signal. b. Check the trigger type: general signals should use "Edge" trigger. Only when the proper trigger type is used, the waveform can displayed stably. c. Change the trigger coupling to high-frequency or low-frequency to filter out the high-frequency or low-frequency noise that interferes with the trigger. (5) No display after pressing RUN/STOP: a. Check whether the mode at the trigger panel (TRIGGER) is on "Normal" or "Single" and whether the trigger level exceeds the waveform range. b. If it exceedsset the trigger level to the middle or set the mode to AUTO. c. Press AUTO button could automatically finish the above setting. (6) Waveform refresh is very slow: a. Check whether the acquisition method is average and the average times are large. b. Check whether the storage depth is the maximum. c. Check whether the trigger release time is large. d. Check whether the trigger is normal and the current time base is slow. e. All the preceding causes slow refreshing of waveforms. Users can restore the factory settings so that the waveforms can be refreshed normally. 10.
