9. Measuring Brix(%)
◇ DO NOT measure any sample that can damage the prism or the
sample inlet unit. Sample temperature should be kept between
10˚C and 50˚C when the power (DC24V) is turned on.
◇ If the sample solution could potentially stain the prism,
immediately clean the prism after measurement (following the
instructions on page 22 of this instruction manual).
① When power (DC24V) is supplied to the CM-BASEα, the Brix(%) measurement starts.
(*) The CM-BASEα has no power switch.
② The Brix(%) value will be displayed when sample flows onto the prism surface.
(*) CM-BASEα(D) also outputs temperature as well.
③ If there is no sample on the prism surface (only air), the red light is on and the error
message LLL will be displayed.
External output relationship is shown in the table below.
m See page 21 if the red light is on even though the prism surface is sufficiently
covered with liquid.
④ The CM-BASEα constantly detects the temperature of the prism. When the sample
temperature is within the range of 10 to 50˚C, the Brix(%) values are automatically
compensated for temperature.
m A left arrow will appear on the screen when the sample temperature is 9.4˚C or
less, or 50.6˚C or more. The Brix values displayed while the arrow is displayed
are not properly temperature-compensated.
⑤ For calibration (zero-setting) see page 19.
