Click the
‘Settings’
icon to display the software options. Note
‘Light
Source’
is not a setting option for the SP-422.
Clicking
‘Calibration’
will display the factory calibrated multiplier
and offset values. These values are saved in firmware and can be
recovered by clicking the ‘Recover Original’ button. Deriving a new
calibration multiplier and offset is accomplished by clicking the
‘Recalibrate’ button. This is applicable if users want to calibrate the
sensor to their own specific light source. Note that a reference
value of the light source is required to complete a recalibration.
After clicking the ‘Recalibrate’ button the user will be prompted to
cover the sensor. Place a dark cap over the sensor and wait for the
real-time shortwave radiation reading to settle at zero. Click OK.
Uncover the sensor and wait for the shortwave radiation reading to
settle
before
entering the reference value. Click OK.
