Starting a measurement and positioning the camera

Hold the device as you would hold a tablet PC and press the Shutter with your right thumb.

Figure 8: Holding the camera and operating the shutter

Place the device approximately 1.2 meters (4 feet) away from the child at eye level. Although
the measurement distance is one meter (3.3 feet), a degree of practice is required to estimate
this distance. It is easier to hold the device a little further away at the start of a measurement
and then to move it slowly towards the child.
Note:
The screen is fixed at a 45° angle to the camera axis. Tilt your wrists downwards to
align the camera.
Pressing the Shutter will start the camera and play back a "warble" sound. You can now see
the camera image on screen.
