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 PAR
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 PAR reading to settle at zero. Click OK.
Uncover the sensor and wait for the PAR reading to settle
before
entering the reference value. Click OK.
The multiplier and offset values will automatically calculate and
update in the appropriate field. Be sure to click ‘Save’ to retain the
new multiplier and offset.
