How to set 1 SUN

1. Shade a sensor head, and set the display value to "0.000" by offset adjustment volume.
2. Illuminate with 1 SUN by your solar simulator to the sensor head,
   (1 sun light intensity has to be confirmed in advance by the user.)
   and set the display value to "1.000" by gain adjustment volume.

3. After the initial settings, you can adjust the light intensity of your solar simulator according to
    the value of them to keep up 1 SUN illumination.*
    *Spectral curve is not considered.
