Internal Paddle
An automated internal calibration feature is implemented by use of
an internal paddle mechanism, which is incorporated within the
Sensor. Black and White Reference materials are mounted within
the Sensor on the paddle assembly and are positioned in front of the
Reflectance Port. The purpose of the internal calibration paddle is to
minimize any instrumental drift caused by aging and/or laboratory
conditions. The internal calibration is reset when you calibrate with
the external standard (Puck). With each sample measurement you
make, the internal standards are also read and corrections are made
for any instrumental drifts that might have occurred.
