The ICUMSA regulates the calibration of polarimeters in SPS-1 (2009) [1]: "To meet the requirements of the statutory authorities or the trade for absolute measurements, polarimeters need to be calibrated. This is basically possible with normal sucrose solutions which can, if necessary, be diluted stepwise to check the whole measuring range.

In making the above exploratory use of the polarimeter, using the sugar solution, you doubtless had to turn the eyepiece clockwise rather than counterclockwise to reach the new extinction point. It is on this basis that sucrose is considered to be dextrorotatory, often shortened to dextrorotary, dextro or d+.
