Timebase. The time between display updates.

Range. The voltage range that corresponds to the width of the screen. A warning symbol ( ) will appear if the input exceeds this voltage.
(Tip: Set the range just above the maximum voltage you expect to measure. Setting it unnecessarily high will reduce the accuracy of your measurements.) |
|
AC/DC Select (ADC-200 and PicoScope 2000 and 3000 series oscilloscopes only). This selects the coupling circuit used in the oscilloscope's input.
(Tip: Set to DC if you need to measure the absolute value of a voltage. Set to AC if you only want to measure the amplitude of a signal, such as its peak-to-peak value, without regard to its absolute DC value.) |

Multiplier. The horizontal scaling factor. Set to "Off" when capturing data, then change to zoom in. You can also zoom in using mouse zooming: hold down the Ctrl key whilst drawing a vertical line downwards with the mouse. The program will select a zoom factor between x2 and x200 according to the length of the line. To zoom out to x2, hold down the Ctrl key and draw a vertical line upwards with the mouse. When you are zoomed in, you can scroll left and right by dragging the scrollbar, or by holding the Ctrl key and pressing the left and right arrow keys.
