5. e is a combo box where the user can select which channel to trig on When a channel is selected a red line is showing in the graph This line is representing the trig value When the value is changed in the value settings the line is also moving There is also a setting for which edge to trig at Up edge or Down edge To start a measure with the trig function press down the PLAY button If the function doesn t find a trig the trig line is red but if the function finds a trig the trig line becomes green The trig value and the edge setting can be changed during a measure Up Edge Down Edge A i Time Window 500 ms Time Window 500 ms Extra funktions Zoom If the zoom button is pressed and the mouse pointer is moved over the x axis or any y axis the mouse pointer is changing shape When this happens and it s on the x axis hold down the left mouse button and move the mouse left to zoom in and move it to the right to zoom out If the mouse pointer it s on a y axis hold down the left mouse button and move the mouse ahead to zoom out and in the opposite direction to zoom in To set the settings back to the default settings press the default button Scroll If the scroll button is pressed and the mouse pointer is moved over the x axis or any y axis the mouse pointer is changing shape When this is happening and it s on the x axis hold down the left mous
