Hi all
Oscilloscope has turned up today I have turned it on and set it to get two lines on the screen connected the probes set them at 10x but get nothing when I connect the tip to the .5v cal I assume the ground wire of the probe needs to be connected to the ground point on the front of the oscilloscope but tried it with and without but just two straight lines Am I doing something wrong.
