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.
• Add distilled or deionized water to the container so the total weight of the solution is 100 g.
• Note: Solutions above 60 %Brix need to be vigorously stirred or shaken and heated in a water
bath. Remove solution from bath when sucrose has dissolved. The total quantity can be
scaled proportionally for smaller containers but accuracy may be sacrificed.
Example with 25 %Brix:

To change the potential alcohol conversion factor, follow this procedure.
1. Press and hold
ON/OFF key continuously for approximately 8 seconds. The LCD will display
all segments screen followed by a screen with the model number on the primary display and
the version number on the secondary display. Continue pressing the ON/OFF key.
2. While continuing to hold ON/OFF , press the RANGE key. The LCD will show the current
conversion factor on the primary display and “ P.ALc ” on the secondary display. Continue
holding the ON/OFF key. Press the ZERO key to increase this number. The number will
continually increase until “ 0.70 ” is reached then wrap back to “ C1 ”. The user selectable
conversion range is 0.50 to 0.70. C1 stands for “curve 1” (see page 6). When you reach the
conversion factor you desire release the ON/OFF key. The new conversion factor will be
used.
