Page 7: Automatic Temperature Compensation
It is however necessary to Allow Samples to Temperature Equilibrate (sample must reach same temperature as prism surface) so that the AR200 can properly correct for temperature. The automatic temperature compensation mode built into the AR200 is based on the temperature coefficients ( ∆nD/∆... -
Page 8: Set Up
Allow the instrument time to reach room temperature. Turn the AR200 on by pressing the “MENU” key. The title screen will appear followed by instructions to apply sample and press read. DO NOT, apply sample or press read at this time. - Page 9 J. Press the “READ” key and note the value on the display, which should be “0.0 Brix-TC, 20.0 C”. Please note that the 0.0 Brix - TC reading can vary by +/ - 0.1 which is the acceptable tolerance of the AR200. 0.0 Brix - TC 20.0 Page 9...

Page 10: Sample Reading
SAMPLE READING A. Clean and dry the prism and well with a soft wipe, which will leave no residue and recommended cleaning agents, soap and warm water, Methanol or Isopropyl Alcohol followed by distilled water. B. Add enough of the sample to cover prism surface and allow adequate time for sample to temperature equilibrate to prism/well. -

Page 13: Multipoint Calibration
10.0 MULTIPOINT CALIBRATION The AR200 can be calibrated with up to 5 points using distilled water and 4 user definable points (note that these are set at the factory to match available NIST certified standards). Performing a 2 point calibration will provide the required accuracy needed, using distilled water and a high refractive index NIST certified standard. -
