21.Common failures and Troubleshooting
Troubleshooting
1.
The oscilloscope doesn’t turn on after pressing the power key
:
1)Check the power cord on the side of the oscilloscope to verify it has been connected
properly;
2) Check the power on/off button to ensure it has been pushed;
3) Then restart the oscilloscope.
If it still does not work correctly, please contact the local distributer or contact Hantek
technology support department directly.
2.
There is no display of waveform on the screen when the oscilloscope is turned
on
:
1) Check the probe to assure its proper connection to the input BNC;
2) Check the channel switch (CH1-CH4 menu buttons) to make sure it has been turned
on;
3) Check the input signal to verify it has been connected to the probe correctly;
4) Affirm that all measured circuits have signals to output;
5) Turn up the magnitude for DC signals with large magnitude;
6) In addition, you may press the Auto Measure button to perform an automatic detection
of signals at first.
If there is still no display of waveform,please contact Hantek technology support
department in time.
3. If the waveform of the input signal is distorted seriously
:
1) Check the probe to assure its proper connection to the channel BNC;
2) Check the probe to assure its good connection to the measured object;
3) Check the probe to verify it has been well calibrated. Otherwise, refer to the content
about calibration described in this manual.
4. If the waveform is rolling continuously on the screen but can not be triggered
:
1) Check the trigger source to make sure it consistent with the signal input channel;
2) Check the trigger level to assure its correct adjustment. You may push the TRIGGER
