Calibrating Lights
If light calibration is needed, the following steps can be taken:
Be sure the reference instrument’s light sensor is a PAR (Photosynthetically Active
Raditation) sensor in units of µmole/m2/s. Place the reference instrument’s light
sensor on the same shelf and right next to the chamber’s light sensor approximately 12
inches (30 cm) beneath the lamps. Be sure that the stabilization times described
earlier have been satisfied prior to performing this calibration.
A positive value will move the light intensity ‘up’ and a negative value ‘down’. Press
the ‘home’ button and verify the proper light intensity is displayed. (See Temperature
Calibration Example.)
Calibrating Optional Chart Recorders
For calibrating the optional front and side mounted chart recorders, refer section 6
