3. Battery Replacement CAUTION When the battery icon indicates the low power level ( ), replace all four ● batteries with a brand new set of AAA alkaline batteries (1.5V). Check the expiration dates on batteries before purchase. ● Remove the battery from the unit when the unit is not to be used for a month ●...
2. Basic Operations CAUTION Operate away from direct sunlight at a stable temperature with as little ● fluctuation as possible. Acclimate both the instrument and sample solution to room temperature to ● ensure accurate results. Measurements may fluctuate with hot or cold samples. Wait to press F after placing the sample on the prism.
2. Measurements ①Wipe the sample stage clean. ②Fill the sample stage with the sample solution to the fill line. Measure room temperature (distilled) samples. The instrument should also Fill line be acclimated to room temperature (Approx. 3mL) prior to operations. Try stirring the sample on the sensor during measurement to improve the repeatability of oily/fatty samples.

5. Scales ANGLE OF ROTATION - Denoted by "α" and expressed in degrees ("° ") The rotation of polarized light is observed when polarized light that is oscillating unidirectionally rotates as it passes through a liquid. The measurement of the angle of such rotation is called the "Angle of Rotation." The angle of rotation is the basic numeric value measured by polarimeters and are dependent on the concentration of the liquid, the length of the observation tube, temperature, and the measurement wavelength.
