Setting the detection area:
The IR-3000 comes with a user modifiable mask on the lens (figure 4) to adjust the width of the de - tection area from approximately 16˚ to 100˚. The mask comes in two pieces, and fits into the slots above & below the lens cover. Each half of the mask is perforated and can broken into three sep- arate strips (figure 4). Each strip of the mask rep- resents approximately 16˚ of viewing angle. The user breaks off the appropriate number of strips to provide the required viewing angle. For example, to monitor a 48˚ angle (figure 5), break off three strips from the mask (3 x 16˚= 48˚).
NOTE: The two halves of the mask do not need to
be symmetrical, a different number of strips can befigure 4 broken off either side.
