Converting Calconstants to Multipliers
For LI-COR sensors that are not type 'SA' (i.e, type 'SB',
etc.), the calibration multiplier must be calculated from the
calibration constant given on the certificate of calibration.
EXAMPLE:
Calculate the multiplier for a LI-190SB
Quantum sensor with a calibration constant of 8.0
