Troubleshooting
1. If the oscilloscope does not start up at power on, follow these steps:
1
）
Check whether the battery is installed and confirm whether the battery level is enough.
2
）
If the battery level is not enough, use the power adapter to charge.
3
）
Restart the instrument after the battery level is enough.
4
）
Contact your local distributor or directly keep touch with 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 (Channel button) 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 button to perform an automatic detection of signals
at first.
7
）
Contact 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 press TRIGGER
button to enter trigger menu, and use Up, Down, Right, Left direction keys to adjust
trigger level to return to signal.
