Chapter 13 System Hints and Troubleshooting

13.1 System Information Description

Operation at limit

：

In the current state, adjustment has reached the limit and cannot continue. When the vertical

scale knob, timing knob, level shift, vertical shift or trigger reaches adjustment limit, the display will show up.

USB device is not inserted

：

When the USB storage device is not connected to the oscilloscope.

Load Failed

：

When the location did not store the setting or waveform needed.

13.2 Trouble Shooting

(1) When the power button is pressed and the oscilloscope is black screen:

a) Check the power supply connection
b) Make sure the power switch at the back of the oscilloscope is open, press the front panel power key and

confirm green light is present

c) If there is a sound, it indicates that the oscilloscope is activated. Try the following operation: press

DEFAULT key, then press F1 key, if device return to normal, it means backlight brightness is too low

d) After completing the above steps, restart the oscilloscope
e) If you still cannot solve this problem, please contact UNI-T and let us serve you.

(2) After signal acqusition, wavform does not appear on display:

①

Check if the probe is connected to the signal test point

②

Check if the signal line is connected to the analog channel input

③

Check the input signal of the analog channel and that channel is open

④

Make sure the probe is connected to the compensation piece and check whether the probe is normal

⑤

Check to see if there is a signal to be detected

⑥

Press AUTO button for signal re-acquisition

(3) The measured amplitude value is 10 times larger or smaller than the actual value

Make sure the probe attenuation coefficient matches the attenuation of the probe used.

(4) There is a waveform but not stable:

①

Check the trigger source in the trigger menu and confirm that the signal and channel are consistent

②

Check the trigger type, normal signals should use edge trigger mode. Stable waveform will be displayed

only by setting to the correct trigger mode

③

Try changing the trigger coupling to high frequency or low frequency in order to suppress or remove noise

caused by interference
