Page 3: Introduction
1 Introduction This refractometer is an easy-to-use measuring instrument. Please read the operating instructions before use to achieve an optimal measurement result. The refractometer is designed for fast and precise determination of concentrations in liquids. Automatic temperature compensation is also included. The measuring in- strument will work reliably for many years if handled correctly. -

Page 6: General Information
4 General information 4.1 Intended use The refractometer is a measuring instrument for determining the refractive index of transparent substances in liquid or in some cases also in the solid state. It is used to observe the behaviour of light as it passes from a prism with known properties to the substance being tested. -

Page 9: Calibration/Zero Point Calibration
8 Calibration/zero point calibration The refractometer's zero position must be inspected prior to initial use and periodical- ly thereafter. A zero point calibration should be performed at least once daily and pri- or to any measurement where the highest possible accuracy is required, or when moving to a different environment with a different ambient temperature. -

mode: 2. Simultaneously press the 'Cal' [6] and the 'Meas' [7] buttons. The measuring instrument will change the measuring scale: 3. When the required measuring scale appears release the buttons again. Adjustment is complete 13 Troubleshooting If you suspect that the measuring instrument is not working correctly or displays in- correct results, perform a zero point calibration. -
