Defective Channel 1, squarewave is different from ch 2
Waveforms are different from each other eventhough the voltage are the same, when the voltage/div is below 2 volts, the square wave form are the same but when i changed it to 5volts, the waveform varies. Also the reading voltage below 2volts is ok but when it increase to 5volts and up, the voltage is not constant.
