Note

It is important to move the probe vertically at a constant rate to obtain an accurate spatially averaged measurement.

5.Proceed to make measurements as normal. To initiate making a spatially-averaged measurement that will be logged, hold the meter in one hand and the probe in the other with the head of the probe touching the ground.

6.Press F1 (START) while slowly moving the probe vertically at a constant rate of movement. Keep your finger on the F1 key during this operation.

7.Strive for an interval of about ten seconds between starting and stopping the timer. The displayed value will flash and the audio signal will sound every second as a timing aid.

8.When the probe reaches the height equal to the top of an adult's head (about 6 ft./1.9 m), press F1 again (STOP).
