3.1.3. MAP Function
The MAP function enables you to map the illumination for a 2-dimensional space or surface. For example, in MAP
mode you can measure the illumination at specific points within a room. You can then download the recording to a
computer running DataView, and display the measurements as a 2-dimensional matrix, creating a "map" of the
illumination within the room.
Before mapping an area, it is good practice to create a chart identifying where to make measurements. For
instance, the following illustrations are example measurement charts for two different rooms.
In the preceding illustrations, gray areas represent illumination sources (such as lights or windows) and red circles
represent measurement points. Consult §4.4 in the standard NF EN 12464-1 for guidance when creating an
illumination mapping chart. To create a map with the Model 1110:
1. Press the MAP button for >2 seconds to enter MAP mode. The counter on the LCD will be initially set to 00
(see below).
2. Place the sensor at the first measurement point and press MEM to record the value in memory. The counter is
incremented.
3. Repeat step 2 for all other measurement points to be mapped.
4. When finished, press MAP for >2 seconds to exit MAP mode.
Note that while in MAP mode, you can use the
measurements made during the mapping session.
Each measurement made during a session is stored in a single MAP file. You can download this file to a computer
running DataView, and display it as a 2-dimensional white-gray-black matrix. The DataView Data Logger Control
Panel Help system explains how to do this (see also §4).
