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

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.
