| Your Own Source. To place your own source, click on the Own Source button and then click in the Source Region. To set the intensity of light of different colors emitted by the source, depress the Select button. Then click on the Open Source Graph button. Position the cursor inside the blue bar at the desired value of blue intensity. The cursor should take the form of a hand (Figure 1). Click once. The bar should fill up to the intensity level you chose (Figure 2).

The method described above is the simplest way to set the light intensity level. You can also set the value using a click-and-drag method. Move the cursor to the zero intensity line below the green bar. Tweek its position until it takes the shape of a double-headed arrow (Figure 3). Then click-and-drag the cursor upward to the desired value of green light intensity (Figure 4).

To show the bars for Infrared and Ultraviolet light intensity, open the background properties and check the box show non-visible light. In the source's Properties Box, under intensity, you can choose to fix the intensity graph so that you can no longer adjust the intensity settings, or you can check change intensity graph, the default setting, to enable the user to modify intensity. If you wish to set the Infrared or Ultraviolet intensity above 10, check the boxes Infrared emission above 10 or Ultraviolet emission above 10. Then select values using the Infrared or Ultraviolet emission level sliding scales (or type values in the fields to the right of the scales). Note: The simulator only accepts values that are multiples of 10. On the intensity graph, a small + above the IR or UV bar indicates that the intensity exceeds 10. You can use the Paste button to replace the default image for the source. The image you choose must first be placed on the CIPS Java Clipboard by the snapshot tool or from the Image Palette.
