Troubleshooting
7.1
Problem Settlement
1.
If the oscilloscope does not start up at power on, follow these steps:
1)
Check the power cord 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.
Contact your local distributor or directly keep touch with our Technical Support department if the oscilloscope still can
not be turned on normally.
2.
If there is no display of waveforms on the screen when the oscilloscope is turned on, follow these
steps:
1)
Check the probe to assure its proper connection to the input BNC;
2)
Check the channel switch (such as CH1, CH2, CH3, 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.
Contact our Technical Support department in time if there is still no display of waveforms.
3.
If the waveform of the input signal is distorted seriously, follow these steps:
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, follow these steps:
1)
Check the trigger source to make sure it consistent with the input channel;
2)
Check the trigger level to assure its correct adjustment. You may push the TRIGGER LEVEL knob or press the
SET TO 50% button to reset the trigger level back to the center of the signal;
3)
Check the trigger mode to confirm it is a right choice for the input signal. The default trigger mode is edge
trigger. However, it is not suitable for all kinds of input signals.
