Too much ambient light detected


Make sure you keep the instrument on the sample until the end of the measurement. Shield the sample to keep light from entering the optics during a measurement on very rough or curved samples. On transparent samples try to prevent light from entering the samples from sides or back. Place sample on a white background.


Instrument requests a "Recalibrate"


Recalibrate the instrument using the Calibrate function in the Settings menu.


"Reference slider not closed!" continually displays after calibrating more than once.


You will need to perform seven calibration procedures in a row. This will set a new reference point and correct the problem.
