Signal Noise

Check if fluctuating light sources (fluorescent tubes, computer
screens) affect the signal.
Exclude that automatic scaling of Y axis at low Y(II) has amplified
signal noise.
6.6

System Hangs

Disconnect line power and remove batteries. Power on again.
6.7

External PAR Sensor is not Responding

Check the following:
External sensor activated (Fig. 48, page 85)?
Correct external PAR sensor selected (Fig. 52, page 89)?
Sunlight profile selected when measuring external light (Fig. 54,
page 90)?
When miniature spectrometer, make sure that the spectrometer
in the light measuring mode (not fluorescence or reflectance).
