Protocol for Making Daily Ultraviolet Readings
using the Sunsor UV Meter

  1. Make a daily UV high reading at solar noon using the Solartech UV meter. The meter reading must occur between the hours of 11:00 a.m. and 1:00 p.m. (12:00 - 2:00 p.m. daylight savings time)

  2. To obtain the UV index instantaneous value, the following instructions will provide the most consistent, accurate results:

  3. Stand clear of buildings, trees, etc. to avoid absorption, diffusion effects of surroundings.

  4. Face the sun direction and hold meter verticle in front of you.

  5. Press and hold button on front of meter case. Note reading on LCD. This value represents the instantaneous UV index.

  6. Fill in the data table below

  7. Record the date of the reading

  8. Record the time the UV reading was taken in military time (24:00)

  9. Weather data for the time of the reading should be recorded below. If you do not have a weather station at school to consult, try an area weather network in your area. Around the United States, and the world, weather data can be obtained from NOAA Weather sites, usually airports that may be near you. This information may be found at National Weather conditions.

  10. Record the sky conditions on the data table - select one of the following
      deep blue
      blue white

Complete all the information on the data table below;
