2. If there is no display of waveform 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 (CH1~CH2 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;

Contact HANTEK Technical Support department in time if there is still no display of waveform.
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 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.
