- Page 10 • Handle instrument carefully. Do not drop. • Do not immerse instrument under water. • Do not spray water to any part of instrument except the “sample well” located over the prism. • The instrument is intended to measure Sucrose solutions. Do not expose instrument or prism to solvents that will damage it.
- Page 11 Calibration should be performed daily, before measurements are made, when the battery has been replaced, between a long series of measure‑ ments, or if environmental changes have occurred since the last calibration. 1. Press the ON/OFF key, then release. Two instrument test screens will be displayed briefly;...
- Page 12 4. Gently absorb the ZERO water standard with a soft tissue. Use care not to scratch the prism surface. Dry the surface completely. The instrument is ready for sample measurement. Note: If the instrument is turned off the calibration will not be lost. Verify the instrument has been calibrated before taking measurements.
- Page 13 3. Press the READ key. The result is displayed in the selected units. Note: The last measurement value will be displayed until the next sample is measured or the instrument is turned off. Temperature will be continuously updated. The ATC tag blinks and automatic temperature compensation is disabled if the temperature exceeds the 10.0-40.0 °C/ 50.0-104.0 °F range.
- Page 14 To make a Brix Solution, follow the procedure below: • Place container (such as a glass vial or dropper bottle that has a cover) on an analytical balance. • Tare the balance. • To make an X% BRIX solution weigh out X grams of high purity Sucrose (CAS #: 57‑50‑1) directly into the container.
- Page 15 To change the temperature measurement unit from Celsius to Fahrenheit (or vice versa), follow this procedure. 1. Press and hold the ON/OFF key continuously for approximately 15 seconds. The LCD will display the “all segment” screen followed by a screen with the model number on the primary display and the version number on the secondary display.
- Page 16 To replace the instrument’s battery, follow these steps: • Make sure the instrument is off. • Turn instrument upside down and remove the battery cover by turning it counterclockwise. • Extract the battery from its location. • Replace with a new 9V battery making sure to observe polarity. •...
