⚫ If it is a DC signal and the amplitude is high, adjust the amplitude gear to a higher value. ⚫ Press the automatic measurement button to automatically detect the signal first. ⚫ If still no waveform is displayed, contact Hantek for technical support. Serious distortion of the input signal waveform. ⚫ Check whether the oscilloscope probe is properly connected with the BNC connector. ⚫ Check whether the probe is properly connected to the object under test. ⚫ Check whether the probe is well calibrated, if not, please calibrate it according to the relevant chapter in the manual. The waveform is constantly scrolling on the screen and cannot be triggered.
⚫ Check whether the trigger source is consistent with the signal input channel. ⚫ Check whether the trigger level is properly adjusted. ⚫ Check whether the trigger mode is appropriate., The default trigger mode is edge trigger, and the trigger should be selected correctly for different input signals.
